Abstract:
An effective method is presented to design the layout of spiral array with ultra-wideband (UWB) grating lobe suppression. In this method, the general array factor expression of spiral array is formulated. Then, the synthesis problem of spiral array layout is converted to an optimization problem of three geometric parameters: s, r and Δϕ. These parameters can determine the exact position of each element. The optimization problem is solved by particle swarm optimization (PSO) algorithm where the constraints of element spacing and array aperture are introduced. For different-sized spiral arrays,

Abstract:
This work provides a guide to design ultrasonic synthetic aperture systems for non-grid two-dimensional sparse arrays such as spirals or annular segmented arrays. It presents an algorithm that identifies which elements have a more significant impact on the beampattern characteristics and uses this information to reduce the number of signals, the number of emitters and the number of parallel receiver channels involved in the beamforming process. Consequently, we can optimise the 3D synthetic aperture ultrasonic imaging system for a specific sparse array, reducing the computational cost, the har

Abstract In the research of multi-sound source localization, the geometric rules for the spatial arrangement of microphone arrays play a decisive role. When faced with multiple sound sources with close positions, traditional typical arrays are difficult to accurately locate the desired signals. Therefore, this paper proposes a leaf-shaped microphone array based on the theory of bionic sunflower spiral arrangement. When the incident signals are multiple sound sources with close positions, combined with the delay-sum beamforming algorithm, the performance of the leaf-shaped array is analyzed fro

Abstract:
In three-dimensional (3D) medical ultrasound imaging with two-dimensional (2D) arrays, sparse 2D arrays have been studied to reduce the number of active channels. Among them, sparse 2D arrays with regular or uniform arrangements of elements have advantages of low side lobe energy and uniform field responses over the entire field of view. This paper presents two uniform sparse array models: sparse rectangular arrays (SRAs) on a rectangular grid and sparse spiral arrays (SSAs) on a sunflower grid. Both arrays can be easily implemented on the commercially available or the custom-made arrays. To s

It is of interest to study slot spiral radiators as part of a phased array with structural elements in the form of multi-layer dielectrics that make up a multilayer substrate and a spiral cover, which, by changing the parameters of a multilayer dielectric, can significantly change the frequency properties of the radiator and its overall dimensions. The purpose of the work is to develop a mathematical model for a phased array in the form of a periodic structure with slotted spiral radiators using multilayer dielectrics in the design, and its numerical analysis with the study of its frequency pr

Abstract:
In this paper, to obtain antenna arrays with grating lobes suppression capability in wideband and achieve a low peak sidelobe level (PSLL), two non-uniform spiral antenna arrays and an enhanced Harris Hawks optimization (EHHO) algorithm are proposed. By controlling the parameters of the spiral line and sampling equidistant on the spiral line, the sampling points that make up the non-uniform array can be arranged in the plane uniformly and non-uniformly. The simulation results indicate that, because of this special arrangement, the non-uniform arrays obtain the capability of grating lobe suppre

Next the array factor is optimized for Directivity only. Then, the excitation is varied for both SLL and Directivity to be optimized.

The use of linear phased arrays in NDE inspections has recently grown, resulting in faster inspection of components. Phased arrays are also used in underwater sonar and biomedical imaging. All applications require 2 dimensional (2D) arrays, capable of volumetric imaging, to further increase scan speed, and to allow tighter focussing on targets. However, 2D arrays have not found widespread use, mainly due to the large number of elements required to implement standard periodic designs. Alternative array configurations that feature a much lower element count offer a more pragmatic solution. This

The Square Kilometre Array is a next-generation radio telescope originally slated to operate at 70 – 450 MHz frequency in its lowest band (SKA-low). This thesis examines aspects of SKA-low station design and finds that two-stage beamforming produces acceptable performance. Additionally, single- and dual-polarised conical spirals are evaluated as candidate SKA-low elements. Though neither versions are strong candidates for SKA, the single-polarised spiral is an excellent antenna for use in Global Epoch of Reionisation experiments.

Abstract:
This work focuses on the design of wideband dual polarized arrays using spiral antennas. These antennas are known for having wideband properties. But, due to the presence of the grating lobes, the bandwidth is decreased when using an array instead of a single antenna. In order to obtain a dual polarized array, it is needed to use elements of opposite polarization, which creates great distances between same polarization elements, meaning an earlier presence of the grating lobes. In this work, an analytic method was developed to estimate the bandwidth of the spiral arrays. This method showed tha

The wideband array with variable element sizes (WAVES) is a multi-octave array that uses different sized circular Archimedean spirals for each octave of frequency coverage. A two-octave WAVES array has been presented in the literature, but a gap in the two-octave frequency coverage exists along the principal axes.

The angle of arrival estimation of multiple sources plays a vital role in the field of array signal processing as MIMO systems can be employed at both the transmitter and the receiver end and the system capacity, reliability and throughput can be significantly increased by using array signal processing.

Another important parameter of localization systems is the array geometry and sensor design which can be application specific and is used to estimate the DOA. In this wo

In spinal cord injured (SCI) individuals the neural pathway between the brain and the extremities is damaged. However, there is still the capacity to elicit muscle activation despite the absence of any supraspinal input. Recent studies have proposed epidural spinal cord electrical stimulation (ESCS) as a means to facilitate locomotor recovery in SCI humans. In epidural stimulation a number of electrodes are placed in the spine, outside the dura, and stimulus current pulses are used to ‘tune’ the spinal circuitries. Some rat studies have supported this concept, but further testing is required t

Abstract:
The field of climate change adaptation metrics is complex and fast-changing. Given the highly contextual nature of adaptation and the array of applied definitions of adaptation and “success”, there is no single global set of adaptation metrics and indicators or definition of adaptation success. There is a burgeoning literature on the Global Goal on Adaptation (GGA), how to measure it and adaptation metrics. However, the landscape is scattered and the subject is very complex. Climate impacts and the effects of adaptation measures themselves spill across national borders, although adaptation is
