• The electric and magnetic field patterns for the dominant mode are shown in fig. The electric field exist only at right angles to the direction of propagation, whereas the magnetic field has component in the direction of propagation as well as normal component.
• The electric field is maximum at the center of waveguide for this mode and drops off sinusoidal to zero intensity at the walls.
• The magnetic field is in the form of loops, which lie in planes normal to the electric field. This magnetic field is the same in all these planes, regardless of position of such a plane along y axis, as evidenced by the equidistant dashed lines in the end view. This applies to all modes.
