摘要：
Wave propagation in a rectangular waveguide with perfectly conducting walls containing a parallel-plane dielectric diaphragm and a small inclusion is modeled using a numerical solution to Maxwell's equations. The methods are developed for reconstructing permittivity of the inclusion from the transmission coefficient of the principal waveguide mode taking into account experimental error. The results determined by these methods are compared with experimental data obtained for a homogeneous diaphragm.
