Comments on "A new finite-difference time-domain formulation and its equivalence with the TLM symmetrical condensed node" [with reply]

For the original article see ibid., vol.39, no.12, p.2160-9 (1981). The commenters summarize the conclusions of the above-titled paper by Z. Chen et al. in five statements. They show that the first four are partly incorrect and the fifth is misleading. In their reply, Chen et al. argue that these five statements are the commenter's conclusions, not theirs. They discuss these statements, agreeing with some of the commenters' points and disagreeing with others.>
