## Abstract This paper presents a 4^th^‐order accurate implicit multistage finite‐difference time‐domain (IMS‐FDTD) method. The analysis of the stability shows that this IMS‐FDTD method is unconditionally stable. In addition, its numerical‐dispersion relation is derived and the analysis shows that
## 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
