The transverse electric and transverse magnetic (TEM) wave traveling in the y-direction charactertized by Ey=0,Hy=0. this means that the electric and magnetic fields are completely transverse to the direction of wave propagation. so electric field have Ez component. because Ez*Hx=Ay(direction of wave propagation) Solution The transverse electric and transverse magnetic (TEM) wave traveling in the y-direction charactertized by Ey=0,Hy=0. this means that the electric and magnetic fields are completely transverse to the direction of wave propagation. so electric field have Ez component. because Ez*Hx=Ay(direction of wave propagation).
