In this paper, a new design method for microwave nonhomogeneous media filte
rs is proposed. The application of this method leads to closed-form design
formulas by which physical properties of the filters can be carried out in
a very fast way. The proposed formulas can be successfully used because the
y are less time consuming than others known in the open technical literatur
e. Some examples of analysis and synthesis are presented. (C) 1999 John Wil
