Author Description

New to this edition are (1) reflection at interface between dielectric and metal, and (2) a long sought for new chapter on relativistic electrodynamics. This new chapter contains a coherent text and math that elucidate use of special theory of relativity in electrodynamics. The text and math start with construction of four vectors of displacement, velocity, volume current density and electromagnetic potential. Lorentz transformations of their components are obtained using (x, y, z, ict) as coordinates. Electromagnetic field tensor has been obtained using which Lorentz transformations of components of electromagnetic fields have been derived analytically (rather than geometrically). The book serves as lecture notes for a one semester course on Electrodynamics for undergraduate students of Physics. The book contains lecture notes of the author which he class tested many times.
