Narrow-band Band-pass Filters for Terahertz Applications

In this work, a WR-1.5 band-pass filter is presented, manufactured using the Polystrata 3D fabrication process. The filter is intended to be integrated into a radiometric receiver to band limit the incoming noise power and encompass an atmospheric spectral window centered at 682.5 GHz. A 10.8 mm diameter waveguide flange is fabricated in Polystrata with a band-pass filter structure running paralle...
