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
danai_pa, I have told you before that you are supposed to show your work when you ask for help. Please see the notice at the top of this Forum. https://www.physicsforums.com/showthread.php?t=4825
