Self-consistent theory of antennas based on integral equations

Neganov V.A., Tabakov D.P.

Abstract

The paper outlines the foundations of a self-consistent theory of antennas. It is shown that the incorrectness of the physical model of the antenna leads to the incorrectness of its mathematical model. Integral representations of the electromagnetic field that become a system of integral equations in relation to the unknown surface current distributions on the emitting area under boundary conditions are proposed as the main instrument of self-consistent analysis. The results of self-consistent electrodynamic analysis for certain types of antennas are presented.

Non-linear image filtration based on Markovian networks with several states

Petrov Y.P., Kharina N.L., Rzhanikova Y.D.

Abstract

Digital half-tone images (DHI) represented by g-digit binary numbers often possess great statistical redundancy which can contribute to increasing DHI reception noise immunity. The paper presents algorithms of DHI non-linear filtration based on Markovian networks with several states that make it possible to reduce the time of image transmission. The filtration algorithms are investigated in the presence of white Gaussian noise. The results of the investigation confirm the theoretical assumptions of the possibility of improving DHI reception quality without the increase in energy resources on the transmitting side of the communication channel.
