We consider a method for calculating the natural wave spectra of round and rectangular shielded waveguides with arbitrary dielectric filling, which is a modification of the Galerkin method and based on the representation of the wave fields of the gui

The vast majority of guiding structures are described [13] by non-self-adjoint electrodynamic operators, which are understood as the totality of the differential equation and the system of boundary conditions. In [15], the conditions for the non-self

Is formulated self-consistently the problem of radiation, which leads to a system of homogeneous Fredholm integral equations of 2nd kind with respect to the fields over the aperture of the emitter. It is shown that this system of equations allows to

The self-consistent boundary-value problem of excitation is considered. In that problem the source function standing on the right side of Helmholtz equation is a solution of the homogeneous boundary value problem for this equation. It is shown that s

The boundary value problem about improper waves of closed waveguide is formulated based on the adjoint of the Helmholtz equation. Shows that this problem is self-consistent, because it takes into account the reverse effect of the field on the source
