We provides quantitative agreement with the experiment of Ref [J.R.Sucking et al,Phys. Rev. Lett. 92, 147401 (2004)], and can account for the effects of the finite conductivity with a small modification to the effective wavelength.
A massive photon possesses a longitudinal polarization mode absent in its massless counterpart. Transverse and longitudinal modes follow different dispersion relations, the latter being much less attenuated than the former when passing…
