Unformatted text preview: unknown permittivity has dimensions a=5cm and b=3cm. If the x-component of its electric field is given by E x =-36cos(40 π x)sin(100 π y)sin(2.4 π x 10 10 t-52.9 π z) Determine: (a) the mode number (b) dielectric constant of the material in the guide (c) the cutoff frequency, and (d) the expression for H y #4. (Textbook 8.40) A narrow rectangular pulse superimposed on a carrier with a frequency of 9.5GHz was used to excite all possible modes in a hollow guide with a=3cm and b= 2cm. If the guide is 100m in length, how long will it take each of the excited modes to arrive at the receiving end?...
