Modified function theoretic technique and its application

This paper extends the modified function theoretic technique (MFTT) to problems which previously can be solved only by other methods such as the moment methods, the geometric theory of diffraction or the generalized scattering matrix technique (GSMT). The increased computational accuracy and the ability to satisfy explicitly all of the edge conditions of a problem appears to be the major advantages of using MFTT. As an example, the radiation characteristics of a five-element, unflanged parallel-plate waveguide is discussed.
