Theoretical Modeling and Electromagnetic Response of Complex Metamaterials

Abstract

In this three year effort, we have made significant progress in understanding complex wave phenomena in artificial materials and metamaterials, and in proposing new exciting opportunities for technology offered by these artificial materials. Details about the various accomplishments can be found in the list of papers funded by this effort, and in the patents and patent applications protecting the new concepts developed during this work. The highlights of our work have been the introduction of the concept of magnet-free non-reciprocal devices based on angular-momentum bias, the concept of Floquet topological insulators for photons and phonons, new concepts based on parity-time symmetric metasurfaces, and various advances in electromagnetic and acoustic theory and applications. Our findings have opened various possibilities for technological breakthroughs, and some of our ideas, developed within this project, have been or are being experimentally verified by our group or other groups. Two of the inventions developed within this project, on which we have made significant progress in the past year, have been licensed to a startup company, Silicon Audio RF Circulator, which is working on the development and commercialization of magnetic-free circulators based on the concepts developed during this effort. We have been working to further improve the performance of these devices over several metrics, and we are excited by the prospect of replacing magnetic isolators and circulators with printed circuit implementations.
