This book begins with an essential background discussion of the many
applications and drawbacks for paraxial beams, which is required in the
treatment of the complex space theory of spatially localized
electromagnetic waves. The author highlights that there is a need obtain
exact full-wave solutions that reduce to the paraxial beams in the
appropriate limit. Complex Space Source Theory of Spatially Localized
Electromagnetic Waves treats the exact full-wave generalizations of all
the basic types of paraxial beam solutions. These are developed by the
use of Fourier and Bessel transform techniques and the complex space
source theory of spatially localized electromagnetic waves is integrated
as a branch of Fourier optics. Two major steps in the theory are
described as: 1) the systematic derivation of the appropriate virtual
source in the complex space that produces the required full wave from
the paraxial beam solution and 2) the determination of the actual
secondary source in the physical space that is equivalent to the virtual
source in the complex space.
