Question 6 [10 marks] Given: the following electric field in phasor form, representing a plane wave propagating in vacuum, Ẽ(z) = (ỹ − jî)e¯jkz V/m a. [4 marks] Find the explicit time-domain form E (z, t). b. [3 marks] From this, show that this is a circularly polarized wave, defining the "sense" of circular polarization, and classify this wave as LHCP or RHCP. c. [3 marks] At time t=0, sketch the evolution of the wave locus along the z axis and comment on the "handedness" of the path in space - is it in the same or opposite sense to the polarisation?
