Abstract :
In this work, we extend ABC into second order in consideration of inhomogeneous medium. The detailed procedure to obtain the second order ABC is described in this paper. Transparent conditions are first established by treating the material properties as functions of position, and the second order ABC is derived from the transparent condition.
