WebSilver, as a noble metal with low loss, has been extensively investigated. The recently developed epitaxial growths of single crystalline Ag on dielectric substrates have prompted efforts to characterize their intrinsic optical dielectric function. WebApr 30, 2010 · A model for the dielectric function of metals is the Lindhard or random phase dielectric constant. well, my point is that: Im eps = 4 pi sigma / omega with eps (omega) = eps (omega,k-->0). This means that for omega --> 0 then I am eps must diverge if sigma is finite, as it is in metals. Or am I missing something ? Apr 29, 2010 #8 Born2bwire
