## Homework Statement

So I have got the question below.

I am asked to find the phase difference between the electric field and magnetic field of electromagnetic waves traveling in a plasma, using the electrical conductivity expression.

Now I have found the frequency of the waves and I know that there is a phase difference between the current and the voltage in the material can be obtained by writing the complex conductivity as A + iB and then finding the angle of that complex number in polar form. What I don't understand is how to calculate the phase difference between the electric field and the magnetic field? Is that the same as phase difference between the current and the voltage?
