ABSTRACT
We develop a general mathematical model for nearfield multipath
scattering as a basis far studying the spatial limits imposed an
multi-antenna wireless communication systems. This model gen-
eralizes the Herglotz Wave Function, which is an important tool in
the study of inverse scattering problems, to a form where the scat-
terers can be nearfield. This permits the development of the most
general form of spatial correlation which is known to constrain the
capacity of wireless systems.
