Altıntaş, A.Russer, P.2016-02-082016-02-0820010018-926Xhttp://hdl.handle.net/11693/24875Time-domain equivalent edge currents (TD-EEC) are developed for the transient scattering analysis. The development is based on the Fourier inversion of frequency domain equivalent edge current expressions. The time-domain diffracted fields are expressed in terms of a contour integral along the diffracting edges for any arbitrary input pulse shape, thereby yielding finite results at the caustics of diffracted rays. The approach also eliminates the need for the evaluation of a convolution integral in the time domain geometrical theory of diffraction (GTD) analysis. The results are compared with the first order GTD results for the transient scattering analysis for a circular disk.EnglishElectromagnetic transient scatteringEquivalent edge currentsHigh-frequency techniques in electromagneticsTime-domain methodsDiffractionElectric currentsFourier opticsFrequency domain analysisIntegrationTime domain analysisGeometrical theory of diffraction (GTD)Time-domain equivalent edge-currents (TD-EEC)Electromagnetic wave scatteringArticle10.1109/8.923321
