The \(\vec E\) field in a rectangular waveguide of inner dimensions a × b is given by
\(\vec E = \frac{{\omega \mu }}{{{h^2}}}.\left( {\frac{\pi }{a}} \right).{H_o}.\sin \left( {\frac{{2\pi x}}{a}} \right).{\rm{sin}}\left( {\omega t - \beta .z} \right)\hat y\)
when H0 is a constant, and a and b are the dimensions along the x – axis and the y – axis respectively. The mode of propagation in the waveguide is
