WebTotal field/scattered field formulation. This paper discussed about another technique that introduces far-zone sources (plane wave) into the FDTD computational domain is the Total Field/Scattered Field (TF/SF) method presented by Umashankar and Taflove. In the scattered field (SF) method, discussed before, the scattered fields are defined in ...

WebThis corner diffraction solution is found by a uniform asymptotic reduction of the plane wave spectral integral formulation for the field scattered by the plane angular sector. An important aspect to this uniform solution is the presence of a UTD transition function which keeps the total high-frequency field bounded and continuous everywhere in the near field outside …
