Radio wave attenuation by a large-scale photonic crystal sculpture

Abstract

Abstract In this work, we present an artwork that embodies the by far largest photonic crystal ever published, operating at radio frequencies. We demonstrate both theoretically and experimentally the existence of band gaps. While photonic crystals are typically investigated on the nano and micro scale, our aim is to present not only a remarkable example of art with scientific relevance but also to highlight the potential for large-scale applications that have so far been underrated.
