Abstract
The paper is devoted to investigation of characteristic properties of electromagnetic pulse signals radiated in the vicinity of conducting screens. A simple two-dimensional model of a reflector antenna has been proposed to study general characteristics of radiation and scattering processes which are important for pulse antenna design. Canonical structures formed by open cylindrical screens excited by a line current source have been studied and numerical results both in frequency and time domains have been presented. It has been shown that the obtained solution to the corresponding boundary value problem is efficient in resonance region and in short-wave band, when dimensions of the screens can vary form several to hundreds wavelength (λ). The reliability and high accuracy of the solution in frequency domain are originated by the rigorous approach that has been applied to the problem. An analysis of scattering in time domain has been carried out on the base of the data in frequency domain using Fourier transform algorithms.
