Interference of Counterpropagating Waves in a “Graphene–Dielectric” Planar Lamellar Structure

Resumo

The incidence of two coherent waves traveling in opposite directions on opposite surfaces of a planar layered-periodic graphene–dielectric structure has been investigated. It has been shown in the long-wave approximation that it is possible to control the intensity of the outgoing waves and absorption of radiation in the structure by changing the phase difference of the waves that are incident on the structure. There are close to optimal conditions for the intensity modulation effect in the terahertz frequency domain and modulation of the absorption capacity of the structure is possible in the near infrared and visible ranges.
