Abstrakt: Low loss SAW filters sometimes require a structure with a complex geometry in order to improve the electro acoustical response (coupling coefficient, reflection coefficient, and static capacitance). Most of the coupling of mode models and P matrix models use parameters obtained from a single electrode periodic transducer analysis. [ABSTRACT FROM PUBLISHER]
