Abstract :
Theoretical impedance modeling of metal whiskers, which are extensively used in millimeter- and submillimeter-wave Schottky diode mixers and frequency multiplier circuits, is presented. The moment method with Galerkin´s technique is employed to analyze this structure with the help of the dyadic Green´s function in a rectangular waveguide. The effects of whiskers with various types of shape on the embedding impedance are investigated. Theoretical results show good agreement with related results published previously.<>
