By using a full‐wave approach, the electromagnetic fields are computed along the propagation path in an irregular spheroidal model of the earth‐ionosphere waveguide. The transmission and reflection scattering coefficients that characterized mode coupling in the perturbed region are shown to satisfy reciprocity. A method is also developed to solve accurately the modal equation in the perturbed waveguide. The advantages of exciting the earth‐detached mode to minimize the effects of mode interference are also discussed.
