Never mind i figured it out \textbf{E} = - \nabla\phi - \frac{d\textbf{A}}{dt} where \textbf{B} = \nabla\times\textbf{A}

so we have the identity \nabla\times\nabla\phi = 0 and from Maxwell's equations we have \nabla\times \textbf{E} = -\frac{d\textbf{B}}{dt} But we also have that \textbf{E} = -\nabla\phi So the problem I'm having is this -\textbf{E} = \nabla\phi which i substitute into the...

lets just go from basics, step by step, assuming everything is complex (sigma E)* . E where E(vector) and sigma(scalar) are complex (sigma)* E* . E = sigma* |E|^2 or sigma* (Ex*, Ey*, Ez*).(Ex, Ey, Ez) = sigma* [|Ex|^2+|Ey|^2+|Ez|^2] = sigma* |E|^2 must take modulus of the field...
