Short summary
We developed a new approach for validation of the numerical models of electromagnetic wave propagation in the Earth–ionosphere waveguide. We compared the parameters of the waveguide (i.e., characteristic electric and magnetic altitudes, resonance frequencies, phase velocity, and attenuation rate) obtained from numerical models with correspondent analytical calculations. We tested such validation for various conductivity profiles and found good agreement between analytical and numerical results.
