This third edition, I gather especially for Dover, is an exceptionally clear and comprehensive presentation of electromagnetic radiation. Years ago my introduction was through Stratton and then Jackson, Stratton gave a great basis for engineers and Jackson was sine qua non at the time. This book is neither of those but a great book for understanding the various EM radiations issues. It presents transmission lines, wave guides, antennas all in the classic manner.The level of presentation is great for either the physicist or the engineer.The authors then continue to present details on interference, diffraction, and relativistic effects. Overall one obtains the depth and breathe necessary to move on to more specific applications.The major strength of the book is the clarity of presentation and the inclusive nature of all key radiation issues.My only negative relates to the extensive nature of the coverage. If one were to present this as a full year senior course, or introductory grad course then there must be a good instructor to balance the information, the book does require some balance, since there is just so much material presented.Overall it contains just about everything one would want to be available, albeit not coverable in a standard class.
