Quasi-stationary analysis of the electric field in anisotropic laminated composites

This paper deals with the analysis of the quasistationary electric field in the presence of anisotropic laminated composites. Both cylindrical and box composite structures are examined in the two-dimensional domain. Two methods are proposed to solve the problem. The first is a numerical procedure employing the finite-difference time domain which uses a direct implicit scheme; the second is an equivalent circuit network which is solved by the use of the standard circuit simulator SPICE. For the composite box structure, the results obtained by means of the two approaches are compared; it is possible to observe a good agreement between them.
