Phys. Rev. Lett. 53, 2169–2172 (1984)Electromagnetic Absorption in a Disordered Medium near a Photon Mobility EdgeReceived 30 July 1984; published in the issue dated 26 November 1984 A frequency regime in which electromagnetic waves in a strongly disordered medium undergo Anderson localization in d=3 dimensions is suggested. In the presence of weak dissipation in d=2+ε it is shown that the renormalized energy absorption coefficient increases as the photon frequency ω approaches a mobility edge ω* from the conducting side as α∼(ω*-ω)-(d-2)ν/2, ν=1/ε. This mobility edge occurs at a frequency compatible with the Ioffe-Regel condition. © 1984 The American Physical Society URL:
