Knott, Shaeffer, and Tuley don't tell us everything about stealth, naturally, but within the limits of a single, unclassified volume this is about as balanced and comprehensive an overview as could be wished. The approach is physical rather than purely mathematical. A good background in electromagnetics is needed for full mastery of the material, but a more limited knowledge of electricity and magnetism will still allow good basic comprehension. Even full mastery of the book won't make you a qualified RCS engineer, but it provides a good basis for further study as well as an excellent resource for those who need an overall design and technology perspective, or must communicate clearly with specialists. I've consulted it over and over in the 15 years since I acquired a copy of the first edition. The second edition has important improvements, although the first edition remains useful in many areas.Will O'Neil
