Abstract :
The EM plane-wave shielding properties of anisotropic laminated composites are analyzed, based on a model that treats each lamina as a homogeneous and anisotropic sheet and then uses a method that cascades the wave-transmission matrices in the computation, Numerical results are presented for graphite/epoxy laminates. In particular, the parameters that influence the shielding effectiveness, such as material properties, laminate thickness, fiber orientation and anisotropy of laminates, and angle and polarization of incident wave, are investigated in detail. For design purposes, empirical formulas are also proposed to estimate the shielding effectiveness of the laminated composites in the lower frequency range
