    Paraxial space - domain formulation for surface fields on large dielectric coated circular cylinders
    (IEEE, 2001-07) Ertürk Vakur B.; Rojas, R. G.
    A space-domain represention for the surface fields excited by an elementary current source was discussed. Green's function was used and an approximation was made using Fourier series (FS), where FS coefficients were calculated using numerical integration. The integrals were evaluated numerically along the real axis using a Gausian quadrature algorithm. However, the developed scheme yielded field expressions that remain valid along the paraxial region for arbitraily small and large separation between observation and source points.
