Which of the following statements is not correct regarding modes of electromagnetic energy transmission?
In TE mode the direction of electric field is always and everywhere transverse to the direction of propagation
In TM mode the magnetic field pattern is always and everywhere transverse to the direction of propagation
The subscripts is TE and TM designations denote the number of half sine wave variations of the field components in x and y directions respectively.
TM11 is called the dominant mode.
