A new volume-surface integral equation method is used for evaluating the bistatic scattering from dielectric cylinders with high dielectric constants. The kernel of this alternate volume-surface integral equations is less singular than the original volume integral equation because it does not require the computation of the double derivative in the highly singular dyadic Greens function. Numerical results indicate that there is a significant improvement in performance by using this new volume-surface integral formulation. We can achieve better accuracy, and require fewer cells per wavelength in the computations than with the original volume integral equation.
