Abstract :
A simplified discussion of propagation in the earthionosphere waveguide is given. It is shown that, if the square of field amplitude is averaged over the width of the waveguide, a very simple formula for the averaged intensity is obtained. This result is used to describe some of the broad features of VLF propagation in a relatively concise fashion.
