Abstract
On the basis of the consideration of a boundary value problem for the associated Helmholtz equation it is shown that the existence of improper waves as oscillations attached to a source is possible in inhomogeneous guiding structures. It is suggested to interpret such boundary value problem as a self-consistent problem, because the inverse field influence on a source is taken into account in it. The example of a self-consistent boundary value problem describing a complex resonance as a special type of improper oscillations is given.
