4-9. The dominant mode TEio is propagated in a rectangular waveguide of dimensions a 2.25 cm and b-l cm. Assume an air dielectric with a breakdown gradient of 30 kV/cm and a frequency of 10 GHz. Ther...
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...
1. Square wave guide Consider a waveguide that is filled with a dielectric that undergoes breakdown (sparking) at an electric field of 10 kV/m. Calculate the maximum power that can be carried by the TE1,0 mode without breakdown if the dimensions of the wave guide are 5 cm by 5 cm. Assume that the frequency is twice the cutoff frequency. Your may express your answer in terms of the index of refraction. 1. Square wave guide Consider a waveguide that...
