From: Transmission characteristics of all-dielectric guided-mode resonance filter in the THz region
Resonance properties of GMR filter. (a) Regions of resonance in the GMR filter. The yellow and green areas indicate incident materials of air and Teflon, respectively. The transmission of TE (red line) and TM (blue line) resonance modes using an FDFD simulation when the incident angle is zero. (b) The incident material is air; and (c) the incident material is Teflon. The field distributions of resonances when the incident material is air: (d) Electric field of the TE0,1 mode; (e) electric field of the TE1,1 mode; and (f) magnetic field of the TM0,1 mode. Black dashed lines are outlines of the structure, with the three unit cells illustrated.
