QUESTION 3 The electric field component of an electromagnetic wave propagating in Air is represented by the following mathematical expression: E(z,t) = ý 0.02 cos(7.5 x 108t – kz) (V/m). (1) Use Maxwell equations to determine the corresponding magnetic field H(z,t). (2) Determine the electric field phasor E(z). (3) Determine the magnetic field phasor H(z).
