Design and development of microwave virtual oscilloscope of complex reflectivity based on electromagnetic approach

A virtual oscilloscope of the complex reflection coefficient, based on the electromagnetic model of the E-plane cross-shaped power divider has been developed. Calibration consisted in grading the power indicators on the matched load,. using the calculated coefficients of the divider scattering matrix. When testing vibrating loads with the module of the reflection coefficient of 0.16, 0.59, 1.0, over the 8-millimeter wavelength range, the obtained error of the reflection coefficient was less than 5%.
