摘要：
In this talk, we discuss the opportunities and potentials of metamaterials in which their constituent elements are modulated in space and time with tailored patterns, or abruptly change in space-time, in order to overcome the constraints of passive, linear, time-invariant materials. We will discuss non-reciprocal and parametric phenomena enabled by these spatio-temporally modulated metamaterials, and emphasize the challenges in efficiently modeling their responses with analytical and numerical techniques. We will also survey several applications of this platform from radio-wave and mm-wave technology to classical and quantum photonics.
