Compensation for the Effect of the Natural Reflection Coefficient of a Directional Coupler in the Multiresonance Method for Measuring the Reflection Coefficient in a Waveguide

“…The approximate formula from [1] relating the sample's RC to the resonance characteristics of the quasi-resonator does not consider the natural RC of a directional coupler, which is determined by the reflection of an electromagnetic wave from the system of coupling holes of the main and detecting waveguides. However, the magnitude of the coupler's natural RC can be as high as several percent [3] and, as was shown by a computer simulation, can introduce a substantial error in the reconstruction of the sample's RC. Below, we describe a method for computational compensation for the influence of the directional coupler's natural RC.…”
