More characteristics or properties of transverse electric and magnetic waves in parallel planes

Last time I have discussed the few characteristics or properties of transverse electric and magnetic waves in parallel planes. Let us discuss more properties of TE and TM waves like cut-off wavelength, guide wavelength, phase velocity, group velocity:

(a) Cut – off Wavelength

גc = υ0/fc

Put the value of υ0 and fc in above equation,

Or                        גc = 1/√ μ0ε0   2 α√ μ0ε0/m

                 גc = 2 α/m

The above is the expression for the cut-off wavelength. Continue reading “More characteristics or properties of transverse electric and magnetic waves in parallel planes”

Waves between parallel planes

Let us discuss how waves propagate through parallel planes and derive the necessary relation of transverse electric and magnetic waves:

Assumptions :

(a)  Pair of parallel planes are perfectly conducting.

(b)  Separation between the planes is ‘a’ meter in x – direction.

(c)  Space between planes is perfect dielectric (σ = 0) of permittivity ε and permeability μ.

(d)  Planes are of infinite extent in the y and z direction. Continue reading “Waves between parallel planes”
