Universal functions for the analysis of electromagnetic interactions in SAW devices

In spite of the availability of a large number of commercial software packages for the analysis of electromagnetic fields, SAW devices defy a satisfying usage of these packages. This defiance is primarily due to the strong anisotropy and the presence of a large number of geometrically complex thin metallic structures positioned on parallel interfaces. The method of moments (MoM) is particularly suitable for this class of problems, despite its deficiencies. To combat several problems in the MoM applications we have developed the method of Fast-MoM utilizing a number of universal functions. In this paper we illustrate the construction and processing of universal functions for the EM analysis in SAW devices, and point out strategies for accelerating the computations and enhancing the accuracy of the numerical results.
