For a resonant impedance wire dipole that is inclined at the angle over a square perfectly conducting screen the conditions guaranteeing formation of a circularly polarized wave with extremely achievable field amplitude in the set directions of the main observation planes depending on the screen sizes are investigated. The asymptotic solution of the 3D diffraction problem of the field of an arbitrarily oriented impedance wire dipole on the rectangular screen, obtained by the uniform geometric diffraction theory method was used. The detailed analysis of the dipole's slope angles, the dipole's removal from the screen, at which a circular polarized wave is formed with extremely achievable field amplitude depending on the screen sizes are given. It is shown that with increasing the screen sizes the interval of angles in the main observation planes at which can be formed the circular polarization considerably increases.

The evolutionary approach is applied to the problem of radiation of impulse transient electromagnetic field from plane disk with homogeneous distribution of given electrical current. The set of evolutionary equations on time and longitudinal coordinate was received from Maxwell equations. The analytical solution of linear problem of plane disk radiation is obtained by Riemann function method in time domain. It is shown the accounting of a weak nonlinearity of a medium by method of successive approximations.

Electric current pulses of nanosecond length and amplitude up to 300 kV traveling through a transmission line partially filled with a magnetically saturated ferrite demonstrate excitation of quasi-monochromatic oscillations at 0.7-2.5 GHz. The amplitude efficiency of this DC-to-RF conversion can reach 50%. The two-dimensional model used for numerical analysis of the non-linear electromagnetic effects in the structure shows good agreement of the calculated and measured results.

The methods of filling the domain of spatio-spectral sensitivity (SSS) are considered. The spectral method for filling the SSS domain in aperture synthesis systems is proposed. It is shown that instead of filling the SSS domain of the serial synthesis using one radio-interferometer with variable base expedient to use fixed antennas and ultra-wideband (UWB) signals processing. The criterion for the uniqueness of the main lobe of the ambiguity function of the two-antenna array using UWB signals processing is obtained.

A method for formulating and solving the inverse scattering problem is proposed. The method is based on the well-known algorithms for pulse signal processing, which are reflected by a plane layered structures. A key feature of the method is to combine the features and benefits of different ways of processing and interpretation of experimental data sets. Used software allowed not only to establish the possibility of solving the problems, but also to optimize the parameters setting process. The results can be used for nondestructive testing and in biomedical research.

A problem of Airy pulse transformation by a plane-parallel layer is considered. Solving of this problem is made by the Volterra integral equation method in two stages. Finding of an electrical field inside a layer is implemented on the first stage. The fields of reflected as well as transmitted pulses are calculated on the second stage. The virtual structure of the pulse field inside the layer consists of some terms one of which extinctions the initial pulse according to the Ewald-Oseen extinction theorem.
