Experimental demonstration of a flexible metamembrane

Abstract

In this letter, we present the experimental demonstration of the modification of the far-field spectral response of a metamembrane using mechanical deformation. The demonstrated metamembrane is a two-dimensional (2-D) metamaterial, created by a free-standing monolayer of periodically coupled artificial atoms. The optical properties of this 2-D metamaterial can be controlled by intentionally applied structural deformation. This experimental demonstration is the first step for developing 2-D artificial materials for sensing and chip-scale spectral analysis applications.
