Comments on "Fields at the tip of an elliptic cone"

Electromagnetic fields near the tip of an elliptic cone can be represented by a sum over a set of vector wave functions. Only the leading terms of this sum contribute to the near field. A useful classification of these terms based on symmetry and periodicity properties of the eigenfunctions of the problem is presented. This classification suggests that there must be a second magnetic field singularity which is not given in the above letter. Data on the related eigenvalue are given.
