Sir why in TEM there is no longitudinal field components along direction of propagation while in TE and TM they have longitudinal components along direction of propagation??
Hz and Ez is zero, not Hx and Ex. Here, direction of propagation of EM wave is considered in Z-direction, so the field components are not present in the Z- direction so, Ez and Hz will be zero. Other field components in the X,Y directions are present. @1.25... look at the diagram shown.
