Inhomogeneous metasurfaces have shown possibilities for unprecedented control of wave propagation and scattering. While it is conventional to shine a single incident plane wave from one side of these metastructures, illuminating by several waves simu

Publisher Copyright: © 2021 IEEE. We derive the dispersion relation of eigenmodes propagating in a time-varying and dispersive medium. We use these eigenmodes to analytically study the scattering of light by a sphere made from a time-varying and dis

Publisher Copyright: © 2021 IEEE. Coherent illumination allows additional flexibility over metasurface functionalities, with coherent perfect absorbers as one typical example. However, most of coherent metasurface devices are based on spatially unif

Conventionally, nonreciprocity in time-varying systems is achieved by exploiting both temporal and spatial modulations. In this paper, we introduce a concept of magnetless bianisotropic time-modulated systems that support nonreciprocal wave propagati

In this talk we introduce the concept of antenna body modulation. We show approximated theoretical formulas for effective resistance and reactance at the carrying frequency and discuss how antenna body modulation can affect them. Finally, we show how

In this talk, we describe excitation of time-varying dipolar particles (time-modulated meta-atoms) by external time-varying fields from a nonstationary and causal perspective. For a time-harmonic excitation, we introduce a complex-valued function, ca

Metasurfaces provide very efficient tools to control electromagnetic waves in all frequency ranges. Unfortunately, their capabilities to control several waves simultaneously is very scarcely discussed in the literature. However, control of two cohere
