Electromagnetic waves scattering on slot systems in rectangular waveguides with arbitrary loads

The work deals with investigation of electromagnetic waves scattering on the slot systems in rectangular waveguides with arbitrary end loads. The linear slotted-guide gratings with slot elements of different kinds, such as longitudinal slots, doubled ones and cross-like slots, are considered. The influence of inner and external mutual coupling and finite wall thickness are taken into account. The solution of the problem under consideration is based on improved and specially modified well-known method of successive approximations.
