High-Power and Wideband Radio-Frequency Dummy Load

A novel approach to designing dummy loads has been proposed that simplifies practical construction and simultaneously offers a satisfactory impedance matching over a wide frequency band for high-power radiofrequency applications. The concept involves a gradual impedance transformation of the guided electromagnetic wave to the short circuit using optimally shaped plates and making use of common tubular non-inductive resistors. Design process involves parametric analysis in a full-wave numerical simulator.
