The limits of applicability of the modified basis induced magnetomotive forces in the scattering problem at longitudinal slot in a waveguide

摘要

The limits of applicability of the modified basis induced magnetomotive forces (IMMF) at approximation of a field of a longitudinal slot in a homogenous and a partly filled waveguides are determined. Influence on the applicability limit value of the IMMF ratio between λ and λg, and also position of the slot on a wide wall of a waveguide is shown.
