waveguide problem 2

danai_pa

In a rectangular waveguide. The time domain expression for transverse electric field component Ex is givien by

Ex = ACos(Pix/a)Sin(2Piy/b)Sin(7pi*10 to the power 10t-kz)

Determining the following

a) Operating mode (mode that pass through waveguidr)
b) Frequency of operation
c) Propagation constant k if the waveguide dimensions are a = 2.3 cm and b
= 1.2 cm. Assume that the waveguide is filled with air
d) Cut-off frequency
e) waveguide wavelength
