摘要：
The finite-difference time-domain method, when applied in cylindrical coordinates, requires special attention when used in close proximity to a modeled structure's axis of rotation. This paper details the derivation of the numerical dispersion relation and stability criterion of this algorithm. This analysis is instrumental in quantifying simulation error sources and in designing the various ancillary modeling tools.
