Resumen

We propose a time-domain analysis of an active medium based on a coupled quantum mechanical and electromagnetic model to accurately simulate the dynamics of silicon-based photonic devices. To fully account for the nonlinearity of an active medium, the rate equations of a four-level atomic system are introduced into the electromagnetic polarization vector. With these auxiliary differential equations, we solve the time evolution of the electromagnetic waves and atomic population densities using the FDTD method. The developed simulation approach has been used to model light amplification and ampl

Resumen

During switching in electrical systems, transient electromagnetic processes occur. The resulting dangerous current surges are best studied by computer simulation. However, the time required for computer simulation of such processes is significant for complex electromagnetic devices, which is undesirable. The use of spectral methods can significantly speed up the calculation of transient processes and ensure high accuracy. At present, we are not aware of publications showing the use of spectral methods for calculating transient processes in electromagnetic devices containing ferromagnetic cores

The quasi‐linear approximation for electromagnetic forward modeling is based on the assumption that the anomalous electrical field within an inhomogeneous domain is linearly proportional to the background (normal) field through an electrical reflectivity tensor λ⁁. In the original formulation of the quasi‐linear approximation, λ⁁ was determined by solving a minimization problem based on an integral equation for the scattering currents. This approach is much less time‐consuming than the full integral equation method; however, it still requires solution of the corresponding system of linear equa

Resumen

Landslides are common geological hazards that often result in significant casualties and economic losses. Due to their occurrence in complex terrain areas, conventional geophysical techniques face challenges in early detection and warning of landslides. Semi-airborne electromagnetic (SAEM) technology, utilizing unmanned aerial platforms for rapid unmanned remote sensing, can overcome the influence of complex terrain and serve as an effective approach for landslide detection and monitoring. In response to the low computational efficiency of conventional semi-airborne EM 3D forward modeling, thi

Resumen

Collaborative dynamics modeling of flexible multibody and rigid multibody for an electromagnetic direct-drive vehicle robot driver is proposed in the article. First, spatial dynamic equations of the direct-drive vehicle robot driver are obtained based on multibody system dynamics. Then, the shift manipulator dynamics model and the mechanical leg dynamics model are established on the basis of the multibody dynamics equations. After establishing a rigid multibody dynamics model and conducting finite element mesh and finite element discrete processing, a flexible multibody dynamics modeling of th

Resumen

Nonlinear microwave imaging heavily relies on an accurate numerical electromagnetic model of the antenna system. The model is used to simulate scattering data that is compared to its measured counterpart in order to reconstruct the image. In this paper an antenna system immersed in water is used to image different canonical objects in order to investigate the implication of modeling errors on the final reconstruction using a time domain-based iterative inverse reconstruction algorithm and three-dimensional FDTD modeling. With the test objects immersed in a background of air and tap water, resp

Abstract Our living environment and the battlefield witness an increase in electromagnetic energy density due to the emergence of electronic electrical equipment, such as automobiles, communication devices, computers. To adapt to the environment and improve the electromagnetic compatibility of equipment, conductive rubber is increasingly being used in electrical equipment. However, due to the lack of simulation parameters and incomplete simulation methods, the current electromagnetic simulation of conductive rubber cannot meet the needs of supporting engineering applications.

Resumen

Electro-explosive device (EED) is easily influenced by electromagnetic interference (EMI) in war-field. To study the electromagnetic susceptibility of EED, the method based on full-wave physical modeling and resonance effect simulation is presented. The EMS of non-contact fuse is analyzed as an example. The test data validate the correction of the EMS analysis method, which is of great value for reference to Electromagnetic compatibility (EMC) design of EED.

Resumen

When creating new objects, reverse engineering technologies are often used. Unlike traditional (direct) engineering, when a product is created from scratch, with reverse engineering, a new product is developed based on a prototype, which significantly saves money and reduces time. The purpose of the study is to systematize and evaluate the main approaches of reverse engineering of modern electromagnetic contactors. Materials and methods. The paper uses comparative analysis and generalization of the results in graphical form, and computer mathematical modeling in the COMSOL software product. Re

Resumen

A new 3D controlled-source electromagnetic finite element (FE) modeling algorithm is presented which is capable of handling local inhomogeneities in the magnetic permeability and electrical conductivity distribution of buried geologic and anthropogenic structures. An ungauged, coupled-potential formulation of the governing electromagnetic vector diffusion and scalar continuity equations is used. The formulation introduces magnetic reluctivity, the inverse of magnetic permeability, to facilitate a separation of secondary and primary potentials. The governing equations are solved using a tetrahe

Resumen

In order to fit circuit electromagnetic emissions within a spectral mask, a design flow based on high level current modeling for micropipeline circuits is proposed. The model produces a quick and rough estimation of the circuit current, thanks to a Timed Petri Net determining the activation instants of the different micropipeline stages and an asymmetric Laplace distribution modeling the current peaks of the activated stages. The design flow exploits this current estimation for shaping the electromagnetic emissions by setting the controller delays of the micropipeline circuits. The delay adjus
