Comments on "Numerical analysis of H-plane waveguide junctions by combination of finite and boundary elements

Abstract

For the original article see ibid., vol.36, no.9, p.1343-51 (1988). In the above-named work, K. Ise and M. Koshiba consider a lossy dielectric post in a rectangular waveguide. In Figures 6 through 10, they compare their results with results published by the commenters (see ibid., vol.35, no.1 p.48-59, 1987) and conclude that their results are more reasonable. The commenters rechecked their results and noted that the results of Ise and Koshiba are indeed the more accurate ones. The inaccuracy was due to the fact that the library subroutine used by the commenters for calculating Hankel functions with complex arguments was defective. >
