Abstract :
The second order accurate FDTD techniques at the dielectric interface is applied to the case of three dimension through the integral form of Maxwell´s curl equations in the nonuniform grids and Taylor series extending of continuous fields component over finite volumes including the interface. The numerical results demonstrate that the proposed algorithm can effectively improve the accuracy.
