Abstract
We present a low cost fabrication method for THz filters utilising a metallic photonic-band gap structure on a plastic substrate. Measurements of the filters are made with a Terahertz Pulse Spectrometer (TPS) and a THz monochromator in the 0.2 – 3 THz range and exhibit absorption band centered at frequencies of 0.72, 0.97 and 1.24 THz, with 3 dB bandwidths of less than 200 GHz. We further present some initial applications of the filters in TPS frequency calibration and explain how such filters can be used as an anti-counterfeiting product.
