Kxe=weh; kxh=-wue how??

For a plane wave of angular frequency o and propagation vector k propagating in the medium Maxwell's equations reduce to (a) k E =0; k H = 0; kxE=øsh; kxH=-ouE (b) k E=0; k H =0; kxE= -os H; kx H =ouE (c) kE =0; k.H =0; kxE= -ouH; k xH=osE (d) k E=0; k.H =0; kxE =ouH; kxH=-wEE
