【Abstract】 Considering one-dimensional nonlinear photonic crystal with metal cladding and using Maxwell’s classical electromagnetic theories,the theoretical analysis model of the electromagnetic wave propagations is founded to obtain the full-wave solutions of the electromagnetic fields.With the boundary conditions satisfied by the electromagnetic fields in the interface between the crystal and the clad,the characteristic equation to describe the band gap structure is deduced.For solving the characteristic equation,the iterative algorithm is proposed.This algorithm provided a theoretical basis for the numerical simulation on the electromagnetic wave propagation characteristics.更多还原
