# Radio wave attenuation by a large-scale photonic crystal sculpture

## TL;DR

This paper describes a large-scale artwork that functions as a photonic crystal, showing it can block certain radio frequencies.

## Contribution

The novelty lies in creating the largest photonic crystal to date at radio frequencies, merging art and science.

## Key findings

- The artwork demonstrates the existence of band gaps at radio frequencies.
- Both theoretical and experimental evidence supports the functionality of the large-scale photonic crystal.

## 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.
