Rays, Waves, and Scattering - John Adam - Bog

"This is a significant contribution to the literature on wave theory, one that blends the mathematics and physics in just the right way. All derivations are given in full so that the work is genuinely a students' book, and Adam has chosen only the most interesting parts of the subject, especially those masterpieces of elegance that draw people to advanced physics in the first place."--C. J. Chapman, Keele University
