“Ultrawideband ribbon antenna array with wideangle scanning” Speaking about the effectiveness of various ways to provide ultrawidebandness and wide angleness of a receiving antenna system (AS), we should note that in an antenna array … 
A variant of constructing an ultrawideband wideangle antenna array based on a multilayer ribbon structure is suggested; the mathematical model of this antenna system is described and the results of numeric modeling are presented.
Speaking about the effectiveness of various ways to provide ultrawidebandness and wide angleness of a receiving antenna system (AS), we should note that in an antenna array (AA) it is usually rather difficult to combine these two properties.
The aim of this work is to suggest a variant of constructing of a receiving AA providing a wide band of operating frequencies and wide sector of operating angles simultaneously. Then, develop a mathematical model of the suggested AA. Based on the constructed mathematical model, conduct a series of numeric experiments to discover the main properties of the AA.

In section of “PublicationsArchive” the “Solution to the threedimensional problem of wave diffraction for a group of solids via the pattern equation method” archival article is published.
Authors: A. G. Kyurkchan, E. A. Skorodumova.
In the article the explicit (asymptotic) solution of a problem is obtained in a case, when the scattering bodies are far enough from each other. It's established, that the obtained approximate analytical solution of a problem is suitable for calculations with an acceptable exactitude at distances between bodies down to their touch, if the sizes of bodies do not exceed a wave length of a field, incident on a group.
