Theoretical model of a microwave Hall-effect empty-cavity signal

A theoretical model of an empty-cavity signal arising from the microwave Hall-effect in the cavity end walls is developed using the S-matrix approach. This unwanted signal is given in terms of the geometry of a critically coupled rectangular bimodal microwave cavity. An expression for the Hall mobility of metals forming the cavity end walls is formulated extending the application of the microwave Hall measurement technique into the area of high conductivity materials.
