- ItemCompact high-power broadband absorptive filters using slotted waveguide harmonic pads(The Institution of Engineering and Technology - IET, 2014-06) Stander, Tinus; Meyer, Petrie; Van der Walt, Pieter Willem; Electrical and Electronic EngineeringA compact high-power broadband absorptive filter is designed by cascading a slotted waveguide harmonic pad with a wide stop-band reflective filter. Absorption is achieved by coupling a surface current standing wave to absorptive external auxiliary waveguides through a cascade of transversal broad-wall slots in rectangular waveguide
