The goal of investigations: the analysis, synthesis and designing of functional elements and wide-band wave systems of SHF, EHF and quasi-optical band with definite electrodynamics characteristics. The consequence of electrodynamics problems were formulated and solved. These decisions allow to create the theory of radiating systems, to develop the beam theory in diffraction problems. The decisions of isolated image guide eigenmodes by single microstrip resonator, systems of resonators with different orientation and electrically-long resonator were obtained by spectral operators' method. The decision of Gaussian's beam diffraction by impedance cylinder was obtained. It was shown the possibility of finite-difference method using in electromagnetic fields modelling problems for quasi-optical devices. A series of experiments were carried out with the helpof modern measuring technique based on automation measuring platform in combination with effective methods of computer technologies for data handling. It allows to confirm several basic theoretical positions in created theories. DIFFRACTION THEORY, WAVE STRUCTURE, EIGENMODE SPECTRUM, ALGORITHM, EXPERIMENT.
