Metamaterial-Dielectric Photonics Crystal Waveguide Structure

Abstract

Photonic crystals (PCs) are a revolutionary science that has a great impact on the field of photonics. In purpose of extend the applications of PCs, we introduce a new photonic structure which is composed of alternating lamellae of MTMs and Dielectric. The electromagnetic waves propagating through photonic crystal structures are numerically investigated. Results show improvement in the characteristics of the photonic crystal.

Sensitivity enhancement of nonlinear waveguide sensors with conducting graphene layer: TE mode

“…Previous attempts to improve the performance of sensors have been introduced [8][9][10][11][12][13][14][15][16]. In order to improve the performance of sensors in practical applications, the sensitivity should be maximized.…”
