Ms. Lin et al., TIME-DOMAIN ANALYSIS OF PROPAGATION IN INHOMOGENEOUS ANISOTROPIC LOSSY SLABS, IEEE transactions on antennas and propagation, 41(10), 1993, pp. 1456-1459
An equivalent-transmission-line-circuit (ETLC) model is developed to d
iscuss the transient propagation problem of a plane wave in inhomogene
ous, anisotropic, and transversely lossy slabs. This model is based on
the analogy between the field equations and the coupled transmission
line equations. By establishing the analogy, suitable lumped-circuit m
odels are proposed to treat the equivalent transmission lines, which m
ay then be solved by the circuit simulation program. In this study, th
e accuracy and convergence of the lumped-circuit models are examined.
The ETLC model is then applied to discuss the propagation problem in a
nisotropic graphite/epoxy laminates with numerical results presented t
o show the transient responses due to the electromagnetic pulse and Ga
ussian pulse.
