Simplifying Digital Array Architectures with Multifunctional Metasurface Apertures

Abstract

Holographic metasurfaces, tailored to exhibit a precise electromagnetic response from a low profile, are a powerful platform for wavefront manipulation and present the possibility to substantially simplify the architecture of increasingly popular (and increasingly complex) digital phased arrays. This article describes the work a Johns Hopkins University Applied Physics Laboratory (APL) team is doing in this area.
