Electrodynamics of superconducting structures

The paper is devoted to developing the electrodynamic theory of superconducting structures and its application to the microwave band. The actuality of the given problem lies in the fact that there are no acceptable mathematical methods, by means of which it would be possible to investigate in sufficient detail and give designers of radioelectronic equipment practical recommendations on solving internal and external boundary value problems (stationary and nonstationary), associated with excitation, scattering and propagation of electromagnetic waves on superconducting (SC) objects of simple and complex shapes. Therefore the development of the electrodynamic foundations of SC structures for external and internal problems with the methods of the spectral theory is an important practical task in antenna and waveguide techniques
