The transmission analogy can be applied to the transverse field components, the ratios of which are constants over guide cross sections and are given by wave impedances. A rectangular waveguide of inside dimensions [a = 4, b = 2 cm] is to propagate a TE10 mode of frequency 5 GHz. A dielectric of constant r=3 fills the guide for z>0 with an air dielectric for z<o.

For f=3 GHz, design a rectangular waveguide with copper conductor and air dielectric so that the TE10 wave will propagate with a 30% safety factor (f = 1.30fc) but also so that wave type with next higher cutoff will be 30% below its cutoff frequency. a = 6.5 cm b = 3.85 cm
