Abstract: Active gain metasurfaces have attracted considerable attention for their capability to convert the “multiplicative fading” inherent in conventional metasurfaces into “additive fading.” ...

Abstract: Metasurfaces have emerged as a transformative technology in modern electromagnetic (EM), yet their design is often guided by empirical approaches lacking a unified analytical framework. This ...

A group of researchers at Penn State developed an approach that integrates artificial intelligence into metasurface design. Their work was featured on the cover of the October issue of Nanophotonics.

A research team at Penn State has introduced a faster, more accessible way to design metasurfaces (engineered materials that can precisely control light and other electromagnetic waves using their ...
