Abstract :
A theoretical model is proposed to study the near-field shielding and reflection characteristics of anisotropic laminated planar composites. Specifically, the plane-wave spectral representation is used to express the dipole field and the wave-transmission matrix technique is employed to deal with the transmitted and reflected fields. In this study, numerical results for graphite/epoxy (G/E) and boron/epoxy (B/E) composites are presented to discuss, in detail, the effects of varying the observation distance, number of layers, lamina thickness, fiber conductivity, and fiber orientation pattern. Comparison with the measured results and the previous published ones are also included to confirm the accuracy of this proposed model
