Community News - Metamirrors

Posted on March 10, 2015

Researchers at Aalto University in Finland have demonstrated a "metamirror", showing that a single layer array of sub-wavelength bi-anisotropic meta-particles can produce reflection at a designed frequency and allow transmission through the structure at other frequencies. Whilst meta-surfaces have been designed to act as mirrors before, the new approach achieves reflection without a metallic ground plane beneath the meta-particle array.
