- K. Davies, Ionospheric Radio, Peter Peregrinus Ltd., 1990. Mostly deals with HF but has a chapter on LF, VLF, and ELF. He provides a general discussion of propagation and then ends up with: "More detailed treatments require extensive use of large computer programs." High school students might find the presentation in this book scary.
- J. K. Hargreaves, The Solar-Terrestrial Environment, Cambridge, 1992. This is a good survey of everything sun to earth. Math is mostly incidental, and you can get the idea by reading the text and studying the figures. Short discussion of VLF (3.5.3) for remote sensing.
- R. A. Helliwell, Whistlers and Related Ionospheric Phenomena, Dover, 1965 (reprinted 2006.) This reprint mostly deals with "natural radio" but has some relevant discussion on earth-ionosphere waveguide propagation. Some terminology is a bit dated. Aimed at a grad student audience.
- R. D. Hunsucker, Radio Techniques for Probing the Terrestrial Ionosphere, Springer-Verlag, 1991. There is a brief discussion of VLF techniques in chapter 9. Background information is more grad student oriented.
