A broadband polarized artificial magnetic conductor metasurface

Abstract

We present an artificial metasurface comprised of a metallic monolayer having a designed functionality of an Artificial Magnetic Conductor (AMC). The metasurface is designed to operate as a broadband AMC for incident electromagnetic waves polarized in a specific direction, while it works as a pass-band filter for waves orthogonally polarized to the previous direction. Hence the design presents a dual polarization-specific functionality, that of a broadband AMC, or that of a transparent dielectric. In this paper we have selected design parameters scaling the AMC behavior at mm-wave frequencies, but the design can be scaled in other frequency bands of choice. A metasurface sample has been fabricated and characterized via Ka-band waveguide measurements which have validated the approach. Applications on antenna substrates have also been demonstrated through full-wave electromagnetic simulations.

H.F. Contopanagos

Harry F. Contopanagos received the B.Sc. (1984) degree from the University of Athens, Greece, and the M.Sc. (1989) and Ph.D. (1991) degrees from the University of Michigan at Ann Arbor, all in Physics, all with top honors. Until 1996 he performed research in Quantum Electrodynamics and Quantum Chromodynamics, as a Postodoctoral Researcher with the Institute for Theoretical Physics, State University of New York Stony Brook and then with Argonne National Laboratory. During that period he developed the theory of Principal Value Resummation and its application to the resummation of gluon radiative corrections. He applied it to the theoretical prediction of the Top Quark production cross section, in excellent agreement with its subsequent discovery and measurements at Fermilab. Since 1996 his research focuses on electromagnetics and microwave engineering, artificial materials, photonic crystals and metamaterials, wireless front ends, antennas and arrays, high-frequency analog IC's and systems-on-chip. He has been a Senior Researcher with the Henry Samueli School of Engineering and Applied Science, University of California (UCLA); Senior Scientist with Hughes Research Laboratories, Malibu, CA; Principal Scientist with the Advanced RF and Mixed Signal Business Unit of Broadcom Corporation, Irvine, CA; Director of Advanced R&D with Ethertronics Corporation, San Diego, CA, a leading manufacturer of embedded multi-band antennas for wireless products. Since 2004 he has been with the Institute of Nanoscience and Nanotechnology, National Center for Scientific Research "Demokritos", Athens, Greece, where he is currently Director of Research. Most recently, he has been Senior Principal Scientist with Energous Corporation, San Jose, CA, under a leave of absence from "Demokritos", where he performed R&D and product development on antennas and arrays in the field of wireless charging. Dr. Contopanagos has authored about 80 papers in refereed journals and conference proceedings and holds 25 issued US and international patents, with several more patents pending.
