Abstract
A microwave low pass harmonic absorber having a main waveguide which passes a desired fundamental frequency. A plurality of shunt waveguides are disposed on the walls of the main waveguide for providing an absorptive path for the harmonic energy. Each of the shunt waveguides includes at least one ridge for lowering the cutoff frequency of the shunt waveguide. In another embodiment, the shunt waveguides include two ridges disposed opposite each other.
