“GuidesArray Circular”

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

 



GuidesArray Circular is supposed for purposes of modeling of phased antenna arrays created using circular waveguides. Such antenna arrays can be used as transmit \ receive antenna systems for radio- and television-broadcast centers, cellular and paging …


With this program you can execute mathematical modelling by the phased periodic plane antennas array from circular 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.

On the basis of the asymptotic theory of diffraction, under the condition of slowness of change in the curvature radii, the mathematical theory of broadband conformal antenna array has been constructed. As an illustration of the operation of this model, the …


When antenna systems are located on objects with curved surfaces, there arises necessity to determine the characteristics of the conformal array (CA) radiators, as the most frequently used components of these systems. The wideband and wide-angle performance can be achieved by means of placing a multi-element array of compact wide-band strip radiators (CWSR) above the impedance structure (IS) with special properties [1], and the use of this impedance structure allows an increase in the radiation resistance, which facilitates matching of the radiator with the feeder line. Since there are well-known difficulties arising during experimental research, there becomes actual a theoretical analysis of CA of CWSR above the impedance curvilinear surface (ICS), as a particular case of IS…
 



In section of “Publications-Archive” the “Solution to the electromagnetic wave diffraction problem using the method of continued boundary conditions” archival article is published. Authors: A. G. Kyurkchan, N. I. Smirnova.


In the article the method of the continued boundary conditions (MCBC) is generalized on three–dimensional vector problems of waves diffraction on bodies of revolution.
