A lossy dielectric has an intrinsic impedance e = 10230' at a particular frequency. If at that frequency the electromagnetic plane wave propagating through the dielectric has its magnetic field intensity defined as: H = ile * costaw + ) Am! a) For this wave the direction of travel is 1 Mark b) For this wave what is the intensity of the electric field?
