News
July 2, 2023: Our preprint titled Agile Free-Form Signal Filtering with a Chaotic-Cavity-Backed Non-Local Programmable Metasurface is online. Therein, we experimentally demonstrate an extremely tunable filter, both in terms of functionality and frequency (spanning the X band and lower Ku band), built off an all-metallic programmable metasurface backed by a chaotic cavity. Our device featuring spatially overlapping resonances and reverberation-induced all-to-all non-locality deliberately forgoes the limiting assumptions of conventional filter synthesis. Along the way, we also confirm multiple predictions from recently developed scattering theories, including the first experimental observation of transmissionless exceptional points.
