Abstract :
A periodic surface-integral formulation is proposed to analyze the reflection and transmission characteristics of a single-layer lossy periodic composite structure for the TE case. Theoretically, the equivalence principle, involving unknown electric and magnetic currents over material discontinuity interfaces, the structure periodicity, and the Poisson summation formula are used to reduce the problem to a periodic cell. These surface-integral equations are solved numerically by the method of moments with pulse bases and point matching. In this study, the numerical results such as reflected, transmitted, and dissipated powers for a single-layer graphite/epoxy composite structure with both circular and square fibers are presented for the TE case. The effects of frequency, incident angle, fiber area, fiber conductivity, and embedding dielectric etc. are examined in detail. Convergence study and comparison with the previous published results are also included to confirm the accuracy of the new formulation
