Abstract : Three numerical integration methods are developed and used for evaluating the highly singular dyadic Green's function in the volume integral equations for scattering from dielectric cylinders. Numerical results indicate that for small permittivities or relatively small dielectric cylinders, the methods are quite efficient and give comparable accuracy. However, when both the relative permittivity and the size of the cylinder are increased, we experienced problems similar to those encountered by a number of previous researchers, namely, the results converge slowly for the TE polarization.
