 P: 4 question For a plane wave of the form E(z,t)=Ee^i(kz-wt) and B(z,t)=Ee^(-kz)*e^i(kz-wt) write down the time-averaged ohmic heating loss per unit volume for any z. 2. Relevant equations J=$$\sigma$$E Maxwell's equations for linear media 3. The attempt at a solution not sure where to start, i need a nudge
 P: 4 Ohmic heating in a conductor ok now i have Re($$\sigma$$) ((Ee^(-kz)e^i(kz-$$\omega$$t))^2)/2 is this right? do i need to simplify if im going to integrate with respect to z?
