#Method for symmetry-breaking in feedback-driven self-assembly of optical metamaterials (Phys. org) If you can uniformly break the symmetry of nanorod pairs in a colloidal solution you're a step ahead of the game toward achieving new and exciting metamaterial properties.
Zhang and his group demonstrated self-assembled optical metamaterials with tailored broken-symmetries and hence unique electromagnetic responses that can be achieved via their new method.
The paper is titled Feedback-driven self-assembly of symmetry-breaking optical metamaterials in solution. We developed an innovative self-assembly route
As a demonstration in our paper we have synthesized a new class of symmetry-breaking optical metamaterials that have isotropic electromagnetic responses
Optical metamaterials harness clouds of electrons called surface plasmons to manipulate and control light. Purdue University researchers had created previously uperlatticesfrom layers of the metal titanium nitride and the dielectric,
the optical metamaterials owe their unusual potential to precision engineering on the scale of nanometers. Quantum computers would take advantage of phenomena described by quantum theory called uperpositionand ntanglement.
