Shielding of E-polarized electromagnetic waves by a closed cylindrical shell

The method of integral equations is used to solve the two-dimensional problem of the diffraction of E-polarized electromagnetic waves by a thin closed cylindrical shell of high but finite conductivity. The integral equations are obtained on the basis of bilateral boundary conditions for the electromagnetic field on the midsurface of the shell. An algorithm for the numerical solution of these equations is proposed, and the near field is analyzed for the excitation for a noncircular shell by a cylindrical or plane wave. Calculation results are compared with experimental data for an aluminum shell.
