Artificial Dielectric Based Antireflection layer for Terahertz Applications

Hajji, M; Zeze, D; Balocco, C; Gallant, AJ

Abstract

We report on experimental and simulation results for low-loss micromachined silicon artificial dielectrics operating as antireflection coating at terahertz frequencies. The artificial layers consist of subwavelength microgrooves with different profiles. Finite-difference time-domain (FDTD) simulations are used to optimize the grating pitch, and to maximize transmission over the frequency range of interest.
