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.

Scott, Love this direct arppoach. It's so simple, it's brilliant. Too often, marketers get caught up in all the details the technology, the platform, the specific messaging. Each of those is imporatant in its own right, but if you don't get the big picture that you need to give people something to talk about it's all for naught. Nice way to get the gears turning on a Friday morning! JamieLeeb7 09/10/09 at 14:34b7Scott, Love this direct arppoach. It's so simple, it's brilliant.
