Analysis and improvement of Liao ABC for FDTD

    Abstract

    Liao's absorbing boundary condition (ABC) is a widely used mesh truncation algorithm as it is valid for all incident angles and is implemented easily even in an inhomogeneous environment. The higher the order of Liao's ABC, the higher its accuracy and its memory requirement. However, Liao's ABC experiences the instability. This paper considers the reduction of data storage requirement and enhancement of the stability.
