We caution that the identification and subsequent replacement of an isotropic chiral medium with an electrically gyrotropic medium by Gilles and Tran [J. Opt. Soc. Am. B <b>19</b>, 630 (2002)] was premised on an incidental similarity. Although the subsequent results of Gilles and Tran reported in that paper are not affected, serious discrepancies would occur if their analysis were applied to different experimental geometries.
