Electromagnetic Energy Transmission and Radiation

This book develops a consistent macroscopic theory of electromagnetism and discusses the relation between circuit theory and filed theory. The theory is developed in successive steps from the Lorentz force, the integral form of Maxwell''s equations in free space, and suitable macroscopic models of polarized and magnetized matter.
