The reflected field is written as an angular-spectrum representation (plane-wave expansion), with an unknown amplitude function A. It is pointed out that A must be considered as a generalized function, and not as a continuous function. Various decompositions of A are suggested and analysed. ...
The Angular Spectrum Representation of Pulsed Electromagnetic Beam FieldsA completely general representation of the propagation of a freely-propagating electromagnetic field into the half-space z z0 > Z > 0 of a homogeneous, isotropic, locally linear, temporally dispersive medium is now considered. The...
The phase-conjugate mirror realized by means of degenerate four-wave mixing in a Kerr-like medium is investigated using the angular spectrum representation of interacting fields. The analysed model is based on the nonlinear mixing of two infinite plane pump waves with the spatially limited probe ...
of diffraction theory has been stimulated by the application of the angular-spectrum representation of the electro- magnetic fields [1-3]. There are also useful applications of the formalism in integrated optics. For instance, the arrangement of different miniaturized elements on a common substrate c...

In Section V.3 tensor operators are introduced and the Wigner-Eckart theorem for the rotation group is stated without derivation. In Section V.4 a new observable, parity, is introduced. Parity is then applied to discuss the spectrum of diatomic symmetric-top molecules. In an Appendix to ...
