Abstract

Abstract : Gyroid metamaterials are chiral network structures that have the potential to be fabricated through block‐copolymer templating. In article number 2200363, Bryan Cote, Vivian Ferry, and co‐workers uncover the contributions of surface and bulk interactions on the circular dichroism spectra generated by this metamaterial design. Surface interactions are found to play a significant role in the circular dichroism of films of silver‐infilled gyroid metamaterials. The dominance of surface interactions allows double gyroids to support strong circular dichroism.
