A new approach to Hurwitz polynomials in several variables

The theory of scattering and related types of Hurwitz polynomials, as well as the role of these polynomials in the theory of multidimensional passive circuits, have been established in previous publications. In the present paper a new approach is developed by means of which the previous results on scattering Hurwitz polynomials can be obtained in a more compact and systematic fashion.
