I enjoy collecting and reading field theory books. Prof. Low's book is very handsome on the outside, and the chapters appear to be enticing on first sight: Electrostatics, Steady Currents and Magnetostatics, Time-Dependent Fields and Currents, Radiation by Prescribed Sources, Scattering, Invariance and Special Relativity, Lagrangian Field Theory, and Gravity. But, with the exception of very, very gifted physics Ph.D. students and authors who've written on this subject, almost everyone will find the book way too difficult to comprehend. Most of the integrals do not specify limits or coordinate systems, and most of the tensor equations don't specify the indices--Prof. Low assumes that the reader can simply figure them out! There are no solved problems, no applications, and the exercises are--for the most part--mini-research projects! Prof. Low says in the Preface that his book is a textbook rather than a treatise, but it sure reads like a treatise. Most students and graduates would be better off studying the Schaum's Outline 2000 Solved Problems in Electromagnetics.
