Solution to the scattering of electromagnetic waves from a dielectric semi-cylinder

The problem of scattering of electromagnetic waves from an arbitrary, infinite dielectric semi-cylinder is treated analytically through a combined dual series and integral equation formulation. It is demonstrated that the numerical implementation of this treatment satisfies the reciprocity relation as well as the electromagnetic boundary conditions. Numerical results are also provided to illustrate the fields generated in the vicinity of the semi-cylinder directly and in the far-field indirectly through the use of radar cross sections.
