Full textThe analysis of radiated emissions from a source throughout the space, is very essential for both dosimetric and electromagnetic interference analysis. The concerns about the latter are growing because of the need to have prediction of the system reliability of the electronic circuits. Moreover the everyday use of devices and systems emitting radio frequency electromagnetic fields is continuously increasing. Some of these devices are operating in the vicinity of human body, and operators are in the near-field region of the radiating source, and they are exposed to electromagnetic fields. For this reason, dosimetric analysis, that shows the necessity of having three dimensional (3D) field mapping in the vicinity of the radiating source, should be performed. For this kind of applications, several scans of the near fields should be done within different planes in order to build the 3D field mapping. Being a challenging process in electromagnetic compatibility studies, near field characterization is being treated by several algorithms that propose different approaches to achieve the required scanning on the radiating source.In this work, we introduce a 3D scanning system with a low cost three axis magnetic field probes. Having such probes allow the simultaneous measure of the three components of the magnetic field based on a single planner scan above the device under test. The designed probes consist of three orthogonal loops combined together; the first probe contains three conventional loops joined in a plastic cube with a total dimension of 10×12×13 mm3, whereas the second probe is a PCB probe printed on an FR4 substrate of 3.2 mm with a reduced dimension of 9×9×3.2 mm3. The designed probes were calibrated with a TEM cell and the corresponding antenna factors were extracted. The presented scanning system uses an oscilloscope as a measuring instrument that gives the possibility of both time and frequency domain measurements. The second part of this thesis presents a reconstruction algorithm based on plane wave spectrum method. In order to reduce the number of scans and hence the time requirements, the presented algorithm requires just a 2D near field scan of the field components, to reconstruct the 3D magnetic field distribution above the radiating device.The third part of the thesis is devoted for the dosimetric analysis of the radiated electromagnetic fields near RFID systems and RF-welding machines. The near-field exposure assessment of the radiated fields from RFID reader antennas operating at 13.56 MHz and used in Libraries was performed. The measurements of the magnetic field near the antenna were established using the designed probes. The results are then analyzed and compared to the regulations in European Directives and ICNIRP Guidelines. Moreover, the exposure to RF electromagnetic fields of workers near RF-welding machines in industrial environment is studied. These machines, operating at 27 MHz, emit strong radiation and the exposure takes place in the near-field region. The spatial distribution of the electromagnetic fields in this region is studied in both numerical simulations and measurements

Full textWith the development of wireless technologies, electromagnetic fields became an important environmental constraint. However, some people attribute symptoms to electromagnetic fields exposure. The results of experimental studies remain controversial due to contradictory results. The aim of this work is to evaluate the effects of a co-exposure between electromagnetic fields and noise. The hypothesis is that co-exposure led to an exacerbation of the electromagnetic fields effects. This work focused on different physiological functions in a juvenile population: sleep, immune system, food intake, respiratory parameters and behavior. The results showed a higher anxious behavior, a decrease of locomotor parameters and an increase in the weight of the animals, associated with variations in the food intake pattern. Sleep is slightly altered in animals exposed to electromagnetic fields. The immune system of animals exposed to electromagnetic fields exhibits alterations in the adaptive immune system by a redistribution of lymphocyte subpopulations in favor of cell activation and humoral immunity, but without variation of the innate immune system. The alteration of immune system was observed during the co-exposure with a different way than noise exposure. This work was the first study to show a variation of immune parameters in juveniles chronically exposed to electromagnetic fields

Full textThis thesis is a contribution to the surrogate modeling and the sensitivity analysis on stochastic simulators. Stochastic simulators are a particular type of computational models, they inherently contain some sources of randomness and are generally computationally prohibitive. To overcome this limitation, this manuscript proposes a method to build a surrogate model for stochastic simulators based on Karhunen-Loève expansion. This thesis also aims to perform sensitivity analysis on such computational models. This analysis consists on quantifying the influence of the input variables onto the output of the model. In this thesis, the stochastic simulator is represented by a stochastic process, and the sensitivity analysis is then performed on the differential entropy of this process.The proposed methods are applied to a stochastic simulator assessing the population’s exposure to radio frequency waves in a city. Randomness is an intrinsic characteristic of the stochastic city generator. Meaning that, for a set of city parameters (e.g. street width, building height and anisotropy) does not define a unique city. The context of the electromagnetic dosimetry case study is presented, and a surrogate model is built. The sensitivity analysis is then performed using the proposed method

Full textPeople are exposed to various types of radiofrequency electromagnetic fields emitted by different wireless communication systems such as broadcast and cellular network. Today, mobile phones integrate multiple antennas so that more than one service can be used at the same time (GSM and WiFi). In the near future, MIMO systems will be integrated into phones due to their advantage in terms of high throughput. This technological expansion is concerned about the health effects due to these new systems. This thesis focuses on the exposure assessment in indoor areas and the representativeness of such a metric which is related to the maximum power emitted from a mobile and from a base station (BTS). In fact, the measurement standard consists of measuring the exposure at "worst case" in order to verify the compliance to the reference levels. Today, we are interested on the real exposure to electromagnetic fields. Measurements and temporal distributions of electromagnetic fields induced by the base stations (downlink) are studied in this manuscript. In addition, exposure induced by cell phones (uplink) integrated multiple antennas near the user head is studied. The objective was to study and analyze the effect of multiple exposures to this type of phones. A new definition of SAR OTA ("Over The Air") is also presented in this manuscript to compare exposures of mobile phones in real conditions. It is been shown that a mobile phone with a low SAR is often a low-performance mobile radio, except MIMO which really helps to reduce the SAR

Full textResearch in non-ionizing numerical dosimetry has been improved thanks to high calculation capacity of computers. These years, integrating variability in the field of dosimetry has become a major issue. Sources of variability are numerous; among them, there are the exposure conditions to electromagnetic radiation which can lead to very different absorbed doses. Indoor channel modeling enables to have a deep knowledge of the exposure conditions of a human body located inside this indoor environment. The aim of this thesis is to develop a statistical method of calculation of the absorbed dose by the human body and to adapt the stochastic channel model to dosimetry. The statistical study of exposure reveals the need to obtain Specific Absorption Rate values for a plane wave exposure for all possible angles of incidence. Taking into account that computation in dosimetry is time consuming, an efficient interpolation method, kriging method, is implemented in order to get whole body Specific Absorption Rate values. Kriging method enables to obtain Specific Absorption Rate for all possible angles of incidence and then to calculate expectation and variance of Specific Absorption Rate. Sensitivity Analysis of expectation and variance to the statistical channel parameters reveals the impact of each parameter. The channel model has been simplified and then adapted to dosimetry by estimating the approximation error induced by this reduction. This thesis answers to the issue of integrating variability in dosimetry in a complex environment and develop the tools that open a new path in studying exposure in any complex environment
