Abstract

A method and apparatus are proposed for operating a microacoustic sensor arrangement, for example, to determine the physical characteristics of a measurement medium. Acoustic surface waves with predetermined wave modes are generated and detected by electroacoustic transducers (6) and a measurement for the physical characteristics of the measurement medium is determined from their propagation behavior along a propagation path. In addition, a sagittally polarized surface wave is generated in the area of the surface of the substrate (5; 22) on which the measurement medium is located.
