Self Assessment Quiz

1. For a guided wave between two infinite conducting  planes separated by a distance of 0.2m.  If the operating frequency is 3.3 GHz, find the number of distinct modes that can travel in the guide.

2. A TE20 mode is propagating along the z direction between two parallel conducting planes separated by 0.2m  along the x- direction. Find the cutoff frequency. Determine λx. If the operating frequency is 2.5 GHz, determine λz and the non-vanishing components of the electric and the magnetic field.  If the operating frequency is 1.2 GHz, calculate the distance over which the strength of the  fields reduce to 1/e of their value.

3. Calculate the rate at which energy is transmitted in a parallel plane waveguide operating in TE10 mode.
