The algorithm of estimating the density of surface magnetic current induced on the array aperture has been obtained as a result of the rigorous solution of the problem of plane wave diffraction on a double periodic array of stripline elements of any shape with passive loads.

Tags: wave , diffraction , current , antenna array Path: Home / Publications / Archives In the paper, the solution method for the problem of electromagnetic waves scattering by cylinder bodies is given. The method is based on 2*piperiodicity property of functions describing the parameters and distributions of fields and currents on cylinder bodies. The method advantage is the possibility of physical interpretation of results. The example of the proposed method application is given.
