Comments, with reply, on "Deterministic approach to full-wave analysis of discontinuities in MICs using the method of lines" by Z. Chen and B. Gao

The commenters points out that in the above-titled paper by Z.-Q. Chen and B.-X. Gao (see ibid., vol. 37, p. 606-611, 1989) equations (16) and (17) can not be derived from expressions (6) to (15). The authors concur with the commenters, but maintain that expressions (7) and (8) are correct.<
