Abstract : An integral equation is given for the electromagnetic field in a dielectric body. The equation is set up for numerical solution for the case of a thin-wall cylindrical shell having finite length. The solution of the integral equation utilizes a truncated Fourier expansion of the field in the shell. The integral equation is enforced at discrete points in the dielectric shell to obtain a system of linear equations in the unknown expansion coefficients. Numerical integration through the shell volume yields the coefficients in the system of linear equations. The system of equations is solved numerically for the expansion coefficients. Calculation of the backscattered fields and the backscattering cross section are then performed. Calculated results are presented for plane wave backscattering from thin-wall cylindrical shells for oblique incidence. The theoretical results show excellent agreement with experimental data for the TE and TM cases. (Author)
