Abstract In this paper, we present a terahertz transmission frequency-selective quasi surface (FSQS) that exhibits strong absorption lines and periodic band-pass characteristic. The FSQS structure is created by laterally combining Fabry-Pérot resonators with different thicknesses. transfer function of the can serve as broadband reference for testing signal integrity path systems. achieves combination characteristics sharp resonances theoretical attenuation over 80 dB quality factors more than 40,000 36 resonators. A single made up four 3D printed fused deposition modeling using low-loss cyclic olefin copolymer (COC) filament. Finally, 3D-printed characterized both frequency-domain time-domain spectroscopy. results show an 42 factor above 100.
