Abstract

We reported the first on the terahertz (THz) transmission characteristics of a guided-mode resonance (GMR) filter made of all-dielectric materials. The measured resonances can be explained by diffraction form the grating surface of the GMR filter, and by guiding along the inside of the filter. The designed GMR filters have a high Q-factor [1], tunable filter [2], and sensor [3]. It is working depend on refractive index, THz beam incident angle, polarization, GMR filter groves periods, and thickness of GMR core. These GMR filters of experimental results were in good agreement with simulation results.
