Substrate Integrated Waveguide
Sebastian Celis, et al., "Simplified Modal-Cancellation Approach for Substrate-Integrated-Waveguide Narrow-Band Filter Design". Electronics 2020, 9, 962. Current substrate-integrated-waveguide (SIW) filter design methodologies can be extremely computational and time-inefficient when a narrow-band filter is required. A new approach to designing compact, highly selective narrow-band filters based on smartly positioned obstacles is thus presented here. The proposed modal-cancellation approach is achieved by translating or eliminating undesired modes within the frequency of interest. This is
