Title:
Experimental Determination of the Complete Scattering Matrix of SAW Reflectors by a New Deembedding Method 
Abstract:
We present a new measuring method which is capable of determining the complete scattering matrix of a surface acoustic wave (SAW) 180° reflector. Additional to the reflector to be investigated only one interdigital transducer (IDT) has to be designed for SAW excitation. These two elements have to be combined in several different arrangements. Exclusively electrical measurements with a commonly used network analyzer are necessary. From these measurements the acoustical two-port description can be...    »
