Abstract: | We report on experiments with two new kinds of microwave resonators for piezoelectric surface excitation of GHz-sound waves. These resonators consist of planar metal structures simply made by photolithography and especially suitable for the higher frequency range where the usual reentrant cavities can be applied no more due to mechanical fabrication difficulties. Moreover, by choosing an appropriate resonator geometry, an electric excitation field with preferred orientation can be generated which allows to enhance or to supress wanted sound modes simply by turning the crystal relative to the excitation structure into an optimum orientation.Supported by Deutsche Forschungsgemeinschaft |
