Comments on "Fast and accurate analysis of waveguide filters by the coupled-integral-equations technique" [with reply]

For original paper see F. Arndt et al., ibid., vol.45, pp.747-60 (1997). In the original paper, the authors analyzed a four-resonator H-plane filter with both the mode-matching technique (MMT) and a coupled-integral-equation technique (CIET). In this paper we applied the MMT utilizing all features described by them to the same filter and verified the total central processing unit (CPU) time. A reply by the original authors to our comment is included.
