Dynamic Electromagnetics

It represents a significant departure from the traditional format of electromagnetics textbooks. In recognition of the importance of dynamics, it deemphasizes electrostatics and magnetostatics, and avoids the need to teach partial differential equations and special functions. Instead, it stresses time variation and wave propagation phenomena. Mathematics used is at the level of elementary integral calculus. Instead of statics, time variation is treated from the start. The focus is on wave propagation, with transmission lines, both transient and steady state, treated in detail. Interpretations are stressed.

As a result of this approach the book is suitable for students preparing for concentration on wireless technology, communications, or high-frequency circuitry (as well as for those who will later specialize in microwaves, antennas, solid state devices, optics, photonics), without overwhelming these students with advanced mathematics.
