Existence of a fundamental tradeoff between absorptivity and omnidirectionality in metasurfaces
Perfect absorptivity coupled with omnidirectionality is a design goal for many absorbers and emitters used in sensing. We report the existence of a fundamental tradeoff between these two quantities in thin metasurface based absorbers.
