Hc. Chu et al., REFLECTION AND TRANSMISSION CHARACTERISTICS OF LOSSY PERIODIC COMPOSITE STRUCTURES, IEEE transactions on antennas and propagation, 44(4), 1996, pp. 580-587
A periodic surface integral formulation is proposed to analyze the ref
lection and transmission properties of a lossy periodic composite stru
cture which has circular conducting fibers embedded in a dielectric ma
trix. This formulation is based on the equivalence principle which rep
resents the unknown electric and magnetic currents over the material d
iscontinuity interfaces, and uses the structure periodicity and Poisso
n summation formula to reduce the problem to a periodic cell, These su
rface integral equations are then solved numerically, using the method
of moments with poise bases and point matching. In this study, only t
he transverse magnetic (TM) case is analyzed and the numerical results
such as reflected, transmitted, and dissipated powers for a single-la
yer fiber-reinforced composite structure are presented, in detail, to
discuss the effects of frequency, incident angle, fiber radius, fiber
conductivity, embedding dielectric, etc. Convergence study and compari
son with the previous published results are also included to confirm t
he accuracy of the new formulation.
