Comments on "Plane wave excitation of an infinite dielectric rod"

In the original letter (see ibid., vol. 4, no. 10, p. 326-8, 1994) Keam provides analytical expressions for the fields inside and outside a lossy, circular cylindrical dielectric rod illuminated by a normally incident plane wave. The author is to be commended for noting the usefulness of analytical methods in studying such problems. However, it appears that a number of important references have been left out and, more seriously, that the computational results are in error. It is the purpose of this letter to correct these deficiencies.<>
