Abstract

Electromagnetic scattering of a Gaussian beam wave from an array of parallel homogeneous anisotropic circular cylinders is presented. The transmitted fields in the anisotropic cylinders are expressed as an infinite summation of eigen-plane waves with different polar angles. The expression of the Gaussian beam is represented as a product of a well-known scattering of a plane wave and a weighting function. The incident field is expressed in local cylindrical coordinates and the scattered field is the summation of contribution of all cylinders. Using the addition theorem of Hankel function, the expression of the scattered field can be transformed from local coordinates to others. By enforcing the boundary conditions on the surface of each cylinder, an infinite set of equations is obtained which can be written in a matrix form. Scattering cross sections and near fields are analyzed and compared finally.
