We investigate the transmission characteristics of THz filters with the localized surface plasmon resonance excited around indium antimonide gratings. First, we use an FR4 substrate with a thickness of $500~mu$m, paying attention to the effect of the loss of FR4. It is revealed that the transmittance becomes quite small due to the inherent loss of FR4. In addition, a high transmissivity cannot be obtained for the filter, even when the thickness of FR4 is reduced to 100$~mu$m. Therefore, we use a silicon substrate, the loss of which can almost be ignored in the THz band. The transmission characteristics are found to be significantly improved, working as a notch filter. However, the Fabry-Perot (FP) resonance is seen in the entire frequency range. To reduce the FP resonance, an anti-reflection coating (ARC) is introduced into the filter. It is shown that the use of the double-layer ARC reduces the FP resonance in the vicinity of the resonance frequency. Finally, we investigate the filters with a moth-eye structure. It is found that the FP resonance is reduced over a wide frequency range, compared with the filter with the double-layer ARC. |
