Special Section Papers

By V. S. Asadchy, M. S. Mirmoosa, A. Díaz-Rubio, S. Fan, and S. A. Tretyakov

This article reviews the long history of research on electromagnetic nonreciprocity, its origins, and its implications. It aims to put into context the recent advances and progress in this area of research, and straighten up erroneous claims on what nonreciprocity actually implies.

By A. Kord, D. L. Sounas, and A. Alù

This article reviews the various available approaches to nonreciprocity available for microwave technologies, from magnetic bias to temporal modulations and nonlinearities, discussing the advantages and draw- backs of each approach in terms of various metrics of performance, and providing a promising outlook for magnet-free nonreciprocal technology at microwave frequencies.

By I. A. D. Williamson, M. Minkov, A. Dutt, J. Wang, A. Y. Song, and S. Fan

This article reviews the use of time modulation to break reciprocity in photonic devices, their various implementations, and potential opportunities for photonic technology.
