Novel integral formulation for scattering from multilayered dielectric cylinders of arbitrary cross section

A novel boundary integral formulation is implemented for the electromagnetic scattering of laser radiation from multilayered dielectric cylinders of arbitrary cross section. Because of the optical frequencies involved, problem size is controlled by a judicious choice of element size. Results for the more compute intensive Galerkin method are generated for comparison against the less time-consuming Moment method using linear isoparametric boundary elements. Singular kernels are integrated numerically using a technique that converges rapidly. Scattered intensities for both TE and TM polarizations on circular cylinders compare extremely well with analytic far-field predictions.
