Power capacity of a rectangular waveguide. (a) Consider a WR-284 rectangular air waveguide with inner dimensions 7.214 cm x 3.404 cm to operate in the dominant mode at 2.45 GHz. Assuming the breakdown electric field of air to be 15 kV-(cm)-1 (with a safety factor of 2 at sea level), calculate the maximum time-average power that can be carried by this waveguide. (b) Another waveguide (WR-430 air-filled, with inner dimensions 10.922 cm x 5.461 cm) is proposed to increase the power-handling capability at 2.45 GHz. Calculate the maximum time-average power that can be carried by this waveguide and compare it with the previous one.
