Abstract : The inverse problem of electromagnetic scattering from a perfectly conducting elliptic cylinder for the low-frequency case is considered. The approach is based on the model technique presented in Boerner and Vandenberghe, conjecturing that the salient features of the scatterer can be determined from the far scattered field via matrix inversion. This follows the low-frequency formulation of the scattered field as given by Udagawa and Miyazaki rather than from an expansion in the elliptic cylindrical wave functions. It is then shown that the characteristic parameters of the ellipse, i.e. the principal axes and the numerical eccentricity can be directly recovered from the expansion coefficients associated with circular cylindrical wave functions, as is presented in Udagawa and Miyazaki.
