Dielectric Interface Conditions for General Fourth-Order Finite Difference

In this letter, two dielectric interface conditions, for narrow- and broad-band simulations, are presented for the general fourth-order finite-difference stencil in the space domain. The effectiveness of both conditions is verified by numerical simulations.
