Discernibility of metallic sphere in rectangular waveguide

This work describes the initial principles of microwave discernibility conditions for metallic sphere, placed at the center of waveguide cross section. Having previously obtained data for this position, low frequencies range for transmission line are in interest. For further clarification, recombination algorithm from free space to line reflection coefficient was developed. New obtained formulation describes in details the behavior of reflection in this diapason. Main interest in discernibility of sphere is the Reyleight region. Natural experiment for 7-12 GHz confirms the findings.
