Loss Studies For Waveguide Based E- and H-plane Bandpass Filters at Terahertz Frequencies
This paper presents a comparative study on the insertion losses for E- and H-plane waveguide-based bandpass filters at THz frequencies. It is shown that the H-plane filters suffer from high loss due to higher surface current on the coupling irises. Finally, two E-plane filters and two H-plane filters with the fractional bandwidths of 2% and 2.5% are designed at 510 and 552.7 GHz, respectively. The filter responses are verified by using two commercially available electromagnetic full-wave simulators. A sensitivity analysis is also presented to estimate the changes in filter responses due to fabrication tolerances.
