Fredholm and Maxwell equations in the confinement of electromagnetic field

Abstract

We recall some results about the confinement of electromagnetic field from the Fredholm's equations properties perspective. Then we review some relations between the Maxwell equations and the generalized Fredholm's equations and show the equivalence between these two points of view when we analyze the change in the broadcasting conditions from confined electromagnetic field to travelling waves, underlying limiting range situations. We propose some general suggestions in order to diminish the waste of power and information when it is necessary some kind of electromagnetic packaging.
