The problem of scattering of a Gaussian beam from an array of parallel circular cylinders is discussed. The cylinders are made of homogeneous isotropic dielectric materials, or perfectly conducting materials, or a combination of both. An iterative scattering technique is developed to evaluate the near- and far-field components. The iterative technique starts with exact series representation of the initial scattered fields from each cylinder due to the incident Gaussian beam. Then, the sum of the initial scattered fields from all cylinders is considered to be an incident wave on each individual cylinder. An additional scattered field contribution is then obtained and successive scattering can take place until the boundary conditions on the surface of every cylinder are satisfied. Transverse electric and transverse magnetic polarized waves are considered, and the effects of the incident beam parameters on the far scattered field pattern are investigated
