Strong gyrotopy in a chiral toroidal medium
N. Papasimakis, V. A. Fedotov, K. Marinov +2
In this letter, we present the first experimental study of a new chiral metamaterial consisting of toroidal wire windings. We show that the metamaterial exhibits three bands of cir…
Coherent and incoherent metamaterials and the order-disorder transitions
Nikitas Papasimakis, Vassili A. Fedotov, Yuan Hsing Fu +2
We demonstrate a new class of "coherent" metamaterials, where a regular ensemble of meta-molecules shows a collective, i.e. coherent, narrow band resonant response, while disorderi…
Coherent meta-materials and the lasing spaser
N. I. Zheludev, S. L. Prosvirnin, N. Papasimakis +1
In 2003 Bergman and Stockman introduced the spaser, a quantum amplifier of surface plasmons by stimulated emission of radiation [1]. They argued that, by exploiting a metal/dielect…
Markovian Memory Embedded in Two-State Natural Processes
Fotini Pallikari, Nikitas Papasimakis
Markovian memory embedded in a binary system is shaping its evolution on the basis of its current state and introduces either clustering or dispersion of binary states. The consequ…
A metamaterial analog of electromagnetically induced transparency
N. Papasimakis, V. A. Fedotov, S. L. Prosvirnin +1
We present a new type of electromagnetic planar metamaterial that exhibit strong dispersion at a local minimum of losses and is believed to be the first metamaterial analog of elec…
