Abstract

We present the THz transmission characteristics of a guided-mode resonance (GMR) notch filter made of all-dielectric material. When the polarization angle for the ideal 1-D GMR filter changes from 0° to 180°, the transmittance variation changes from 0 to 1 as a function of cos2 (Φ), where Φ is polarization angle. However, if the second filter is installed at a rotation angle between 0° and 90° compared to the first filter, then the transmittance ranges for the polarization angles change from 0 to any value less than 1.
