Abstract
This paper presents a detailed analysis of transient response of electromagnetic pulse (EMP) and Gaussian pulse in anisotropic laminated composites. To this end, both the equivalent-transmission-line-circuit (ETLC) model and the finite-difference time-domain (FDTD) method are adopted in the time-domain analysis. In this study, numerical results are presented for graphite/epoxy (G/E) laminates, based on a model which treats each lamina as a homogeneous and anisotropic sheet. The factors to influence the transient response of anisotropic laminated composites, such as laminate thickness, fiber orientation, and the angle, frequency contents, and polarization of incident wave, are also investigated. © 1993 IEEE
