Abstract : After a general discussion of non-harmonic electromagnetic processes from the viewpoint of temporal Fourier (or Laplace) analysis and synthesis, a class of problems is considered for which the transient solution may be recovered in simple form. Included in this category are pulsed point, line and plane wave sources in free space, and in the presence of (a) a dielectric half-space, (b) a perfectly absorbing or perfectly conducting wedge or half plane, and (c) a unidirectionally conducting infinite and semi-infinite screen. Explicit expressions for the transient response, found by a systematic application of the modal procedures discussed in earlier chapters in this sequence, are interpreted in physical terms. Attention is then given to a second class of problems wherein an electric charge moves uniformly along a straight trajectory in various environments. The associated radiation is now of the Cerenkov type, and formulas for the fields as well as the radiated power are given. (Author)
