# permittivity and conductivity vs. attenuation [closed]

Is there any direct relationship between permittivity of a medium and attenuation of an EM wave? What about conductivity vs attenuation?

edit: Ok for instance an EM wave traveling in sea water. I get that due to conductivity the ions would induce an opposite E field to cancel out the EM wave thus attenuating the wave, but I'm really confused on an intuitive understanding of the permeability of a medium.

• This could take several different routes to give a full answer and probably leave you baffled. Why don't you consider trying to be more specific about a particular problem. Very short answer to above is "Maybe and yes". – Andy aka Jun 8 '15 at 12:47

$\hat\epsilon = \epsilon\prime - j\epsilon\prime\prime$
