Use MATLAB to make the following plots of fields associated with propagating modes in a rectangular waveguide. The dimensions are a=2.3 cm, b=1.0 cm and the frequency is 18 GHz. Assume that the maximum electric field is 10mV/m.
a) Plot Ey as a function of x for the TE10 mode, for t = 0 and for t = 1.39 x 10^-11 seconds and z = 0 and y= b/2.
b) Plot Ey as a function of z for the TE10 mode, for t = 0 and for t = 1.39 x 10^-11 seconds and x= a/2 and y= b/2.
c) Repeat (a) and (b) for the TE11 mode.
