Unformatted text preview: field is given by E x =-36cos(40 x)sin(100 y)sin(2.4 x 10 10 t-52.9 z) Determine: (1) the mode number and the cutoff frequency, (2) dielectric constant of the material in the guide (3) the expression for H y (4) the power it carries on this mode (5) other modes which may also propagate (6) how long does it takes if one transmits information from one end of a 100m long waveguide to the other end with all these modes? 3) Draw the field templates for all the magnetic field components of TE 20 mode and TM 12 mode in a rectangular waveguide. If one wishes to insert a thin film of PMC into the waveguide like shown in the following figure, where would he place it without disturbing the original field distribution for either case above?
