Magnet-Free Non-Reciprocal Metamaterials Based on Spatio-Temporal Modulation
Abstract
The overall objective of our MURI program has been to introduce and develop revolutionary concepts to model, design, analyze, fabricate and characterize magnet-free non-reciprocal metamaterials for the next generation of integrated electromagnetic and photonic systems. Over the past three years, our team has been introducing an entirely new paradigm for nonreciprocal technology, pushing the limits in terms of efficiency, isolation, insertion loss, integrability, size, cost, noise, power handling and scalability. In the past five years, we have been addressing the fundamental issues currently limiting non-reciprocal metamaterial devices, in particular in the context of their bandwidth of operation and metrics of performance, opening completely new pathways towards integrated magnet-free technology that outperforms magnet-based isolators, circulators, gyrators and other relevant devices over all metrics of interest for various applications of relevance to the DoD, including radar, communications, quantum computing and nanophotonics. In parallel, we have also been opening a new paradigm in the context of metamaterial technologies based on temporal modulations, unveiling new wave phenomena in time-modulated metamaterials.
