Abstract
Wave equations and Helmholtz’s equations are three-dimensional vector partial differential equations. In Chapter 2, the uniform plane waves are discussed, where the three-dimensional vector Helmholtz equations are reduced directly to one-dimensional scalar differential equations. The telegraph equations given in Chapter 3 are also one-dimensional scalar differential equations. The solutions of both equations are one-dimensional traveling-waves.
