Surface Currents Induced by an E-Polarized Wave on Curvilinear Strips
ABSTRACT
The problem of scattering of an E-polarized electromagnetic wave by a cylindrical strip which cross-section is an arc of a smooth curve, has been reduced to a singular first-kind integral equation in reference to the surface current density. The obtained equation is convenient both to apply the mechanical quadrature method and to transform this equation into a second-kind equation by the regularization method. A wide class of arcs is studied. The class includes both parabolic arcs and quite compound arcs which have many extreme points. Besides a general dynamic model of the problem, a quasi-static model is proposed. This model admits a simple explicit solution. Numerical calculation and comparison of the results are given.
