Compressive Sensing Based Sparse MIMO Array Optimization for Wideband Near-Field Imaging
Shuoguang Wang, Shiyong Li, Ahmad Hoorfar +3
In the area of near-field millimeter-wave imaging, the generalized sparse array synthesis (SAS) method is in great demand. The traditional methods usually employ the greedy algorit…
Inverse-designed Metastructures Together with Reconfigurable Couplers to Compute Forward Scattering
Vahid Nikkhah, Dimitrios C. Tzarouchis, Ahmad Hoorfar +1
Wave-based analog computing in the forms of inverse-designed metastructures and the meshes of Mach-Zehnder interferometers (MZI) have recently received considerable attention due t…
Efficient Antenna Optimization Using a Hybrid of Evolutionary Programing and Particle Swarm Optimization
Ahmad Hoorfar, Shamsha Lakhani
In this paper, we present a hybrid of Evolutionary Programming (EP) and Particle Swarm Optimization (PSO) algorithms for numerically efficient global optimization of antenna arrays…
Antenna Optimization Using a New Evolutionary Algorithm Based on Tukey-Lambda Probability Distribution
Vahraz Jamnejad, Ahmad Hoorfar
In this paper, we introduce a new evolutionary optimization algorithm based on Tukey's symmetric lambda distribution. Tukey distribution is defined by 3 parameters, the shape param…
RPCA-Based High Resolution Through-the-Wall Human Motion Detection and Classification
Qiang An, Shuoguang Wang, Wenji Zhang +4
Radar based assisted living has received great amount of research interest in recent years. By employing the micro-Doppler features of indoor human motions, accurate recognition an…
Range-Max Enhanced Ultra-Wideband Micro-Doppler Signatures of Behind Wall Indoor Human Activities
Qiang An, Shuoguang Wang, Ahmad Hoorfar +4
Penetrating detection and recognition of behind wall indoor human activities has drawn great attentions from social security and emergency service department in recent years since…
Peano High Impedance Surfaces
John McVay, Ahmad Hoorfar, Nader Engheta
Following our previous work on metamaterial high-impedance surfaces made of Hilbert curve inclusions, here we theoretically explore the performance of the high-impedance surfaces m…
