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 10tkz) 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) Cutoff frequency e) waveguide wavelength
