Opportunities for Millemeter-Wave Wireless Technologies Using Metasurfaces

Abstract

In this talk we review our recent progress on the opportunities enabled by metamaterials and metasurfaces for mm-wave wireless technologies. We will discuss our recent work in the context of time modulation and spatio-temporal variations in metasurfaces, with particular attention to the tools they offer to overcome the common limitations of passive, linear, time-invariant systems. More broadly, we discuss how metasurfaces integrated with active, nonlinear and time-varying elements may disruptively advance mm-wave wireless communication systems, offering new tools for reconfigurable intelligent surfaces that can tailor the incoming spectrum, and reconfigure at will the communications channels with large flexibility. We envision new programmable multifunctional surfaces with ad-hoc communication protocols for new opportunities in mm-wave technologies.
