AM = Acupi(kin - cut ) a ) Why does an electromagnetic wave such as this have 2 independent states of polarisation? " ) Using maxwell's equations show that cilkil? =wr . ( ) Now, suppose 24 = (0, 1, i, 01. Derive E E B. d ) This plane wave hits a surface at 2= 0, that conducts perfectly along x and not at all along y. Find aup expression for the potential that would be reflected from this surface
