Abstract :
An exact theory is developed for fields due to currents in the presence of an anisotropic slab. The anisotropy is of a type expected of a composite reinforced with unidirectional fiber and is described by a diagonal matrix in Maxwell´s equations. A Green´s matrix is defined with exact and explicitly computed solutions to Maxwell´s equations for point currents. The Green´s matrix reduces to quadrature the problems, in frequency and time domains, of computing the field produced inside and outside a slab by arbitrary current sources. Steady-state AC current sheets and loops are considered, and numerical results are presented
