A Contrast-Source Inversion Scheme Based on Stochastic Optimization and Plug-and-Play Regularization
Lingqi Gao, Hakan Bagci
An electromagnetic inversion scheme that integrates stochastic optimization (STO) and plug-and-play (PNP) regularization into contrast-source inversion (CSI), termed STO-PNP-CSI, i…
A Sparsity-Promoting Electromagnetic Inversion Method Regularized by -Norm of the Model Gradient
Lingqi Gao, Hakan Bagci
A nonlinear EM inversion method regularized by -norm of the model gradient is proposed. The -norm, defined as the ratio of -norm to $\ell_…
Characteristic Mode Analysis of Composite Nanostructures using a Coupled System of Volume Integral and Hydrodynamic Equations
Meruyert Khamitova, Ran Zhao, Doolos Aibek Uulu +2
Full-structure and sub-structure characteristic mode analysis (CMA) formulations are developed for composite metallic--dielectric nanostructures based on a coupled system of volume…
Physically Consistent Channel Modeling and Signal Processing for Reconfigurable Wireless Systems
Ahmad Dkhan, Simon Tarboush, Hadi Sarieddeen +3
Reconfigurable antennas are increasingly integrated into multi-antenna communication systems to exploit large apertures while reducing the hardware complexity, energy consumption,…
Characteristic Mode Analysis of Plasmonic Nanostructures Using Hydrodynamic Volume Integral Equation
Meruyert Khamitova, Ran Zhao, Doolos Aibek Uulu +2
Metallic nanostructures confine electromagnetic fields at subwavelength scales, making them attractive as plasmonic nanoantennas. At these scales, the response of metals becomes no…
A Single-Trace Surface Integral Equation Solver for Simulation of Open Bianisotropic Metasurfaces Described by Generalized Sheet Transition Conditions
Sebastian Celis Sierra, Junze Shao, Ran Zhao +3
A single-trace surface integral equation (SIE) solver incorporating generalized sheet transition conditions (GSTCs) is presented for the simulation of three-dimensional (3D) open b…
A Multi-Frequency Iterative Method for Reconstruction of Rough Surfaces Separating Two Penetrable Media
Ahmet Sefer, Ali Yapar, Hakan Bagci
A numerical scheme that uses multi-frequency Newton iterations to reconstruct a rough surface profile between two dielectric media is proposed. At each frequency sample, the scheme…
