Dynamic Electromagnetics (Paperback)

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.

BENEFITS

• Covers: transmission lines; plane waves and polarization, including oblique incidence (and dependence on polarization); boundary conditions, with and without surface source distributions, with and without conductivity; calculation of characteristic impedance (almost never done in other texts); impedance matching techniques; matching for power transfer compared with matching to eliminate reflections; quasistatic analysis emphasizing corrections to circuit-theory results; optical topics: Snell's laws, Brewster's angle, total internal reflection (and its relation to fiber optics); Poynting theorems (real and complex) and power transfer.
• Includes discussions of: microstrip lines; superconductors; plasmas; space charge; normal modes; cavities; optical activity; Smith chart; antireflection coating; dielectric waveguides; grazing incidence (and relevance to wireless communications); dispersion; group velocity; antenna terminology.
• Appendix reviews (with illustrative problems): complex numbers; coordinate systems; vector algebra; dyadics; vector calculus; Fourier transforms, convolution; decibel scale.
