Executive Search für die IT-BrancheThis book has been entirely devoted to . electrodynamics. However, we live in a quantum world, so it is fitting that we end this volume with a discussion of the quantum nature of the interaction of charged particles with the fields in a microwave cavity, represented here as a harmonic oscillator.

,Maxwell’s Equations,Electromagnetic phenomena involving matter in bulk are approximately described by the Maxwell field equations, in SI units,

Patrimony

Spherical Harmonics,Although spherical harmonics will not appear explicitly in the sequel, it seems impossible to write a textbook on the subject of electromagnetic theory without a brief account of some of their most fundamental features.

Transmission Lines,In this brief chapter we shall consider some simple elements of low-frequency transmission lines, and a prolegomenon to the considerations, in the following chapter, of waveguides. Following the preceding chapter, we will here, and in most of the following chapters, assume harmonic time dependence through the implicit factor e..

Rectangular and Triangular Waveguides,To illustrate the general waveguide theory thus far developed, we shall determine the mode functions and associated eigenvalues for those few guide shapes that permit exact analytical treatment. In this chapter we will discuss guides constructed from plane surfaces. Circular boundaries will be the subject of Chap. 8.
