dc.description.abstract	A terahertz (THz) bandpass filter has been presented in this manuscript based on frequency selective surfaces (FSS). The presented structure is very simple and of compact design with various rectangular metallic patches, showing a bandpass characteristics in THz region lying between 6.4 THz and 23.9 THz. The structural design along with the evolution of the geometrical shape of the unit cell has been discussed. The center frequency of the filter is around 15.15 THz with 3-dB bandwidth of 17.5 THz. The structure provides ultra-thin nature and can be used for spectroscopy and imaging applications in infrared domain. © 2019 URSI. All rights reserved.
