Abstract

I comment on the recent paper by Setälä <i>et al</i>. [J. Opt. Soc. Am. A <b>18</b>, 678 (2001)]. In that paper the calculation is entirely and exactly adopted from our previous work except the evanescent-field propagator. I shall demonstrate that the replacement of the propagator flaws the calculation. In their paper the numerical results show rich subwavelength information at absolute far-field distances (four times larger than the wavelength). I shall point out that the evanescent resolution at far-field distances cannot be of subwavelength. In the paper by Setälä <i>et al</i>. the description of previous work is inaccurate and misleading. I shall give what I consider to be the correct guidelines for readers to learn about the standing controversy regarding the evanescent field of a dipole.
