A periodic surface integral formulation for single-layer composite structures (TE case)

A periodic surface integral formulation for TE case is proposed to treat the transmission and reflection characteristics of a single-layer periodic composite structure which has square conducting fibers embedded in a dielectric matrix. This formulation makes use of the equivalence principle to represent the unknown electric and magnetic currents over the material discontinuity interfaces, and then uses the structure periodicity and Poisson summation formula to reduce the problem to a periodic cell. A convergence study and comparison with the previous published results are included to confirm the accuracy of the new formulation.
