    This is a lovely book. It is an advanced and highly technical text on the analysis of real-life E&M engineering systems. It is engineering oriented. You won't find treatment of traditional physics-oriented E&M topics here, such as Kramers-Kronig relations, particle beams, or relativity--see Jackson for those. You will find plenty of waveguides, resonators, microwave networks, propagation and scattering, and antennas.

    Topics here are grouped somewhat unconventionally by mathematical technique. Scattering, waveguide and antenna problems are scattered (if you will) throughout multiple chapters depending on their geometry, for instance. It works fine this way, once you get used to it.

    Some of Harrington's coverage is particularly good, and hard to find elsewhere. The treatment of reciprocity is deeper than usual, and I have found the rarely treated Rumsey's reaction theorem to be useful. Harrington was, above all else, a computational wizard and his chapter on perturbation and variational methods is excellent. (His book "Field Computation by Moment Methods" is still the go-to reference more than 40 years after it was published.) He also makes frequent use of Green functions.

    I had a traditional physics education, using Jackson among other texts. Since starting to work in industry on antennas, communications and radar, and microwave systems, I am more likely to pull down the books by Harrington, Stratton and Collin.

    In summary, this is an excellent advanced engineering E&M text. Others can perhaps comment on its suitability for the classroom. I can attest that it is well suited to self-study.

    I strongly agree with marcusl. This really is a nice book to learn applied EM from - I have come across this book only since I have been out of grad school and working in radar, but have found that it is a great book. Chapters 1 and 2 basically review, in a quick manner, undergrad engineering electromagnetics (basics of waves, elementary antennas, guided waves). Chapter 3 is a really nice discussion of many of the basic "theorems" that can be useful for applied EM work - both for exact and approximate solutions of Maxwell's equations. Chapters 4-6 on waves in different coordinate systems (not so unlike the organization of the middle of Stratton's book which predates Harrington) covers guided waves, radiation, and scattering. Both exact and approximate solutions are included. Like marcusl, I really like chapter 7 on approximation techniques. His explanations are very clear and he doesn't get lost in teh algebra. I have not really read Chapter 8, so cannot comment on it.

    One thing I like about the book is that it isn't nearly as long as Balanis' book (advanced engineering electromagnetics); it is a manageable size while still covering a lot of ground. The book is a little old fashioned, but is by no means out of date. Harrington may be less encyclopedic, but he is also much less tedious and more interesting, in my opinion.

    I must agree with marcusl: the books by Harrington and Collin are truly superb for applied EM, with the exception of Harrington's undergrad electromagnetic engineering book which isn't even worth the Dover price in my opinion. Stratton was apparently a physics book of yesteryear, but much of the coverage, at least after the first couple of chapters, fits right in with mainstream engineering electromagnetics these days. I must say that I look at Stratton mainly for fun, though, while Collin (especially is antenna and radiowave propagation book, and foundations for microwave engineering) and Harrington (just this book - I never have built my own moment simulations!) have come in handy at work on multiple occasions.

    The prereqs for Harringtons book is upper level undergrad EM, and standard applied math that all physics/engineering students take (vector calculus, differential equations, complex numbers). Complex analysis shows up in a couple of hte problems (if I recall correctly deriving a version of Kramers-Kronig is the subject of one such homework problem ...), but in general you do not need to know it for this book, so it is suitable for many folks with standard undergrad backgrounds.
