> Recently, there has been a growing interest in time modulated metamaterials. [1] These materials exhibit dynamic changes in their properties over time, representing a novel approach to manipulating waves and processing information. This approach goes beyond the constraints imposed by energy conservation and time-reversal symmetry. Time-switched and time-varying metamaterials, as they are also called, enable us to access the momentum and frequency of the waves, leading to a wide array of unique properties, such as time-refraction, [2] time-reversal, [3] nonreciprocal behavior,[4] wave synthesis and frequency conversion, [5,6] and amplification. [7] Time modulated metamaterials have potential for application in communication, security, sensing, and computation just to mention a few, across various wave domains from electromagnetism to acoustics and mechanics.
