Extreme Beam-forming with Impedance Metasurfaces Featuring Embedded Sources and Auxiliary Surface Wave Optimization
Gengyu Xu, Vasileios G. Ataloglou, Sean V. Hum +1
We present the end-to-end design of compact passive and lossless metasurface (MTS) antennas with integrated feeds. The complete low-profile system consists of a single-layered reac…
Extreme Beam-forming with Metagrating-assisted Planar Antennas
Gengyu Xu, Sean V. Hum, George V. Eleftheriades
We present a highly efficient metagrating-assisted antenna (MGA) architecture with a simple integrated feed. Power from a localized line source is distributed throughout the arbitr…
An Efficient Integral Equation Method for Full-wave Analysis of Inhomogeneous Electromagnetic Surfaces with Connected Conductors
Reza Gholami, Parinaz Naseri, Piero Triverio +1
In this paper, a generalized macromodeling approach is presented to simulate complex electromagnetic (EM) surfaces consisting of unit cells with connected conductors. Macromodels o…
A Combined Machine-Learning / Optimization-Based Approach for Inverse Design of Nonuniform Bianisotropic Metasurfaces
Parinaz Naseri, Stewart Pearson, Zhengzheng Wang +1
Electromagnetic metasurface design based on far-field constraints without the complete knowledge of the fields on both sides of the metasurface is typically a time consuming and it…
