Nonreciprocal Phased-Array Antennas
J. W. Zang, A. Alvarez-Melcon, J. S. Gomez-Diaz
A phased-array antenna is a device that generates radiation patterns whose shape and direction can be electronically controlled by tailoring the amplitude and phase of the signals…
Wideband Bandpass Filters Using a Novel Thick Metallization Technology
Celia Gomez-Molina, Alejandro Pons-Abenza, James Do +4
A new class of wideband bandpass filters based on using thick metallic bars as microwave resonators, instead of common microstrip lines, is presented. These bars provide a series o…
Nonreciprocal Yagi-Uda Filtering Antennas
J. W. Zang, X. T. Wang, A. Alvarez-Melcon +1
This paper proposes a novel and compact nonreciprocal filtering antenna based on temporal modulation. The device is composed of a third order filtering section integrated into a Ya…
Non-Reciprocal and Collimated Surface Plasmons in Drift-biased Graphene Metasurfaces
D. Correas-Serrano, J. S. Gomez-Diaz
We explore the unusual non-reciprocal and diffraction-less properties of surface plasmon polaritons propagating in drift-biased graphene-based metasurfaces. We show that applying a…
Coupling Matrix Representation of Nonreciprocal Filters Based on Time Modulated Resonators
A. Alvarez-Melcon, X. Wu, J. Zang +2
This paper addresses the analysis and design of non-reciprocal filters based on time modulated resonators. We analytically show that time modulating a resonator leads to a set of h…
Giant Lateral Optical Forces on Rayleigh Particles near Hyperbolic and Extremely Anisotropic Metasurfaces
N. K. Paul, D. Correas-Serrano, J. S. Gomez-Diaz
We report a dramatic enhancement of the lateral optical forces induced on electrically polarizable Rayleigh particles near hyperbolic and extremely anisotropic metasurfaces under s…
