Electromagnetic scattering from periodic arrays of composite circular cylinders with cylindrical inclusions

A very efficient and accurate method to characterize the electromagnetic scattering from periodic arrays of 2D composite cylindrical objects with eccentric cylindrical inclusions is presented, using the lattice sums formula and the aggregate T-matrix. The dielectric host cylinder per unit cell can contain two or more eccentric cylindrical inclusions, which may be dielectric, conductor, gyrotropic medium, or their mixture with different sizes. The power reflection coefficients from one-layer or one-hundred-layered periodic arrays of composite cylinders with two inclusions have been numerically studied.
