## Abstract In this paper, an improved finite‐difference time‐domain (FDTD) algorithm is proposed in order to eliminate the restraint by the Courant–Friedrich–Levy condition. The new algorithm is developed based on an alternating‐direction implicit (ADI) approach. In this method, the conventional t
## Abstract It is well known that the numerical dispersion relations of all kinds of finite‐difference time‐domain (FDTD) methods, including the conventional FDTD and alternating‐direction implicit (ADI) FDTD methods, are derived from the assumption of plane wave. In the past, however, disregarding
the boundary and the interior regions. Thus, it may be concluded that a chiral absorber provides an efficient and simple boundary termination for the FDTD method. ## Conclusions In this work, we have investigated the possibility of using a chiral absorber to terminate the grid in an FDTD scheme. T
