“GuidesArray Coaxial”

With this program you can execute mathematical modelling by the phased periodic plane antennas array from coaxial wave guides in sector of angles and a band …

 



GuidesArray Coaxial is supposed for purposes of modeling of phased antenna arrays created using coaxial waveguides. Such antenna arrays can be used as power transmit \ receive antenna systems in various areas of radio-engineering.


With this program you can execute mathematical modelling by the phased periodic plane antennas array from coaxial wave guides in sector of angles and a band of frequencies.
The offered mathematical model is founded on an electrodynamic solution of a boundary task in a unit mesh of infinite structure.

A method for solving boundary problems of electrodynamics for convex periodical antenna arrays by reduction to analogous boundary problems for flat surface using an iterative procedure is examined.


The work [1] describes one of the variants of the boundary layer method, based on the asymptotical solution of the bound system of parabolic equations, directly following the Helmholtz equations. The solution itself is constructed as quadratures (or rows), which is composed of Airy functions on the conditions that the conformal surface with impedance structure (SIS; surface S) has large electric size.
 



In section of “Publications-Archive” the “The Algorithm and Results of Calculating the Characteristics of Waveguide Radiator Arrays” archival article is published. Authors: E. M. Privalov, Z. K. Kudrya, S. D. Gorina.


In the article the method and algorithm of calculating the input characteristics for the radiators of antenna arrays with a small number of radiators have been developed.
