https://doi.org/10.1057/9780230614130the solution to the source-free wave equation. Starting with Chapter ., we assumed that a wave was generated in some fashion but did not concern ourselves too much with how the wave was generated. Occasionally, the term “source” or “antenna” was mentioned but only to indicate that the wave must have a source.

Vector Calculus,ons that use integrals and derivatives. The rules needed for these evaluations constitute vector calculus. In particular, line, volume, and surface integration are important, as are directional derivatives.

Transients on Transmission Lines,nic representation. Voltage and current were phasors, and a number of properties such as the speed of propagation, wavelength, and phase and attenuation constants were used as a direct consequence of the time-harmonic nature of the waves. Much of the discussion paralleled that of propagation of plane waves in unbounded domains.

,Coulomb’s Law and the Electric Field, start looking into the physical phenomena of electromagnetics. It will be useful to keep this in mind: The study of electromagnetics is the study of natural phenomena. There are two reasons why it is important to emphasize electromagnetics as an applied science. First, it shows that it is a useful

,Gauss’s Law and the Electric Potential,pter, we address two issues: one is to formalize some of the results obtained in the previous chapter and the second is to expand on the ideas of electric field intensity, electric flux density, and the relation between the electric field and material properties.
