These lecture notes on electromagnetism have evolved from graduate and undergraduate EM Theory courses given by Professor Ashok Das at the University of Rochester. The basics of the subject are taught with the clarity and attention to detail that are characteristic of all of Ashok DasĄŻ books.

The 13 chapters cover, in considerable detail, topics ranging from electrostatics and magnetostatics, to plasmas and radiation. Boundary value problems are treated extensively, as are wave guides, electromagnetic interactions, and fields.

All in all, this set of lecture notes, written in a simple and lucid style, and in a manner, which is complementary to other texts on electromagnetism, will be a valuable addition to the physicist's bookshelf.

Ashok Das is a remarkable teacher. He is precise and exceptionally clear. His arguments are logical and impeccable, which is why all his students love him. AshokĄ's lecture notes on Electromagnetism contain the essence of the subject, and reflect his care for clarity of content and simplicity in style.

Thomas Ferbel (University of Rochester)

Professor Das has done a superb job of explaining electricity and magnetism in his new book which is bound to become a classic. Clear, readable, and accuate, DasĄ's book takes the reader through all the important developments in electrodynamics.
