✦ Synopsis

be easily realized with a single metal insert within a rectangular waveguide. Measured frequency responses of a rectangular waveguide E-plane bandpass filter which used quarterwavelength metallic septa shows 30 dB rejection at 36 GHz. The central resonator was resonant at 36.8 GHz. This kind of resonator is expected to find application, particularly, in the millimeter-wave, submillimeter-wave, and terahertz range circuits, e.g., in low-phase-noise oscillators and highly selective filters, diplexers and multiplexers, frequency-selective surfaces, and antennas.
