A design theory is described for waveguide E-plane inductive strip filters that takes the high-order mode interaction, and the finite thickness of metal with a dielectric substrate underneath into account. The main idea was to use superconducting material, instead of metal, in the design of inductive strip insert filters. A design method is introduced for this purpose, and high-T/sub c/ superconducting (HTSC) films serve as perfect conductors. An X-band bandpass filter was fabricated with HTSC materials. The measured results of the HTSC bandpass filter are presented and compared with the CAD-predicted filter performance. >
