It is often necessary to change the physical direction of propagation or the wave's polarization in waveguides. What is the purpose of a twist section?
A)To produce shunting reactance across the guide
B)To change the plane of polarization of the wave
C)To change the physical direction of propagation
D)So low received power does no damage to the powerful transmitter output

Question

A twist section is used to change the plane of polarization of the wave. It rotates the electric field of the wave by 90 degrees, which changes the plane of polarization.
