This introduction to electromagnetic theory emphasises on applications in electronic engineering. The book explores the relationship between fundamental principles and the idealisations of electric circuit theory. Attention is drawn to the effects of parasitic capacitance and inductance, to electromagnetic screening and to the effects of propagation delay. The text includes numerical and approximate methods for calculating resistance capacitance and inductance. With its clear presentation of both theoretical and practical topics this is an ideal introductory text for degree students.
