Characteristics of semiconductor diodes as power indicators are studied. Rigorous electromagnetic model of direct problem of average detection is derived. Approximate models of the inverse problem for detector characteristic are proposed. Maximum errors of approximation for different orders of approximating polynomial and source resistance are calculated.
The problem of creating meter of complex reflection coefficient based on the electromagnetic approach using E-plane dividers is studied. A rigorous electromagnetic model of direct and inverse problems of five- and six-port measurements of complex reflection coefficient is derived. Frequency dependencies of model parameters are calculated. Properties of E-plane junctions are investigated. Approximations...
