Metamaterial analogue of the Mossbauer effect

Not Accessible

Abstract

We report on intriguing behavior of an electromagnetic metamaterial that presents a phenomenological analogue of the Mossbauer effect, where the metamaterial resonance becomes narrower and stronger with increasing number of meta-molecules in the array structure, similarly to how the broad gamma-emission line collapses in crystalline media Such behavior was observed in both the microwave and THz parts of the spectrum in the so-called trapped-mode metamaterial, a high-Q metamaterial that has recently been introduced by the authors [1] and shown to have a range of interesting applications characteristic to essentially quantum systems, such as lasing spaser [2] and metamaterial analogue of the electromagnetically induced transparency and the Fano resonances [3].
