Consider a rectangular waveguide of dimensions x = a and y = b, the wave travelling along the z-direction, the axis of the guide. Given that the z-component Hz satisfies the equation (d2/dx2+d2/dy2)Hz=(k^2-w^2ne)Hz (a) obtain the solution for Hz . (b) Obtain the cut-off frequency. (c) What are the similarities and differences between TMmn mode and TEmn mode? |
