Hk. Chiu et al., PROPAGATION MODELING OF PERIODIC LAMINATED COMPOSITE STRUCTURES, IEEE transactions on electromagnetic compatibility, 40(3), 1998, pp. 218-224
A new model based on filament-current and thin-current assumptions is
proposed to analyze the propagation problem associated with the lossy
periodic multilayer structure of conducting fibers situated in a diele
ctric matrix. To discuss the combined effect of fibers and dielectric
matrix, reflection and transmission matrices at the air-matrix, and gr
ating interfaces together with suitable phase correction are incorpora
ted in the model in which the fiber grating is regarded as a thin Floq
uet layer. To reduce the central processing unit (CPU) time, an extend
ed filament-current model for the same multilayer structure is also ex
amined. In this study, numerical results for the graphite/epoxy (G/E)
fiber-reinforced planar laminated composite materials are presented an
d discussed. In particular, the parameters that influence their shield
ing and reflection characteristics are investigated in detail. The new
model is useful in characterizing the G/E fiber-reinforced laminated
composites even up to the higher frequency of 100 GHz.
