Time-varying metamaterials and metasurfaces have unlocked a novel way for the electromagnetic waves to interact with artificial materials. In this contribution, we present an overview of the recent components and devices based on time modulation of artificial media, surfaces, and illumination signals for achieving time-domain devices, magnet-less non-reciprocity, doppler cloaking, frequency conversion, and virtual energy accumulation into open cavities, respectively.

Abstract
Time-varying metamaterials and metasurfaces have unlocked a novel way for the electromagnetic waves to interact with artificial materials. In this contribution, we present an overview of the recent components and devices based on time modulation of artificial media, surfaces, and illumination signals for achieving time-domain devices, magnet-less non-reciprocity, doppler cloaking, frequency conversion, and virtual energy accumulation into open cavities, respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
