Solving of the applied problems of propagation of electromagnetic waves is often connected with the search of analytic solutions to the boundary value problems of mathematical physics. From this viewpoint, the use of variable division method is one of possible …


An obvious example of realization of advantages of the generalized Fourier method GFD [1] over the classic one in solving of applied electrodynamics problems is the problem of hollow triangular cross section waveguide (Fig.1), whose envelope is considered to be a perfect conductor, while the inner medium is homogeneous. In the most cases, this model turns out to be satisfactory in practical calculations. If necessary, it can be made more accurate by accounting for the losses in the metal.
 



In section of “Publications-Dissertations” the “Phase synthesis of special-shaped beams in phased antenna arrays of airborne radars” dissertation is published. Author: A. N. Gribanov.


The aim of the dissertation is to find, develop and research the methods of the phase synthesis of special-shaped beams for phased antenna arrays on airborne radars, including forming beams spread in one and two planes and of the “cosec 2 (θ)” type.
