- W4313596477 abstract "AbstractWe present a novel architecture for very thin Frequency Selective Surfaces (FSS) and waveguide passband filters based on resonantly transparent super-thin printed screens, transversely placed on the waveguide axis. The screens are based on stacked metal laminate layers where each layer is the negative print of each adjacent layer along the propagation axis. Hence, these filters are composed of stacked layers obeying the Babinet duality. We provide two optimized designs of such filters, operating both as Frequency-Selective Surfaces and as finite screens placed transversely inside a rectangular waveguide. We show that these optimized designs have very small thicknesses, relative to their performance. Therefore, they are an attractive candidate for replacing traditional bulky and heavy waveguide filters based on sparsely placed metallic posts along a substantial length of waveguide sections.KEYWORDS: Passband filtersfrequency selective surfaceswaveguide filtersBabinet dualitymm-wave technology Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsHarry F. ContopanagosHarry 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 the field of Quantum Electrodynamics and Quantum Chromodynamics, as a Postdoctoral 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 & 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 for 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 work on Antennas and Arrays in the field of wireless wireless charging. Dr. Contopanagos has authored about 80 papers in refereed journals and conference proceedings and holds 25 issued U.S. and international patents with several more patents pending." @default.
