Numerical solutions of some parametric effects due to electromagnetic wave scattering by an infinite circular cylinder

Abstract

The analytical solutions for the scattering of electromagnetic waves from an infinite circular cylinder and refractive index are programmed in FORTRAN (Barber and Hill, 1990). The resulting quantities include the scattering coefficients, the scattering amplitudes and the intensities. The range of variable input parameters (Aperture, size parameters, scattering intensities, efficiencies and inverse size parameters) are discussed and presented. Their respective effects were also presented. At 0o, alternate resonance was observed. The alternate resonances disappear at 90o. The resonances are also emphasized at 180o while the intensity for TM (Transverse Magnetic) polarization is continuous across the surface and that of TE (Transverse Electric) polarization is discontinuous.
