专利汇可以提供Unidirectional surface wave transducers专利检索,专利查询,专利分析的服务。并且Disclosed is a unidirectional interdigitated surface wave transducer having at least three discrete arrays of conductive elements, each array comprising, in a comb-like structure, a plurality of electrodes electrically interconnected in parallel and having a periodicity corresponding to one acoustic wavelength of the resonance frequency of the transducer. The discrete arrays of electrodes are deposited upon a piezoelectric substrate in an interleaved pattern to define an interdigitated transducer. Respective electrodes of a given array are substantially equidistantly spaced apart from electrodes of the other arrays and are electrically insulated therefrom. The arrays of electrodes are positioned upon the substrate such that there are at least three electrodes per acoustic wavelength at the resonance frequency. A voltage of different phase is simultaneously applied to each array of electrodes by means of novel broadband phase shifting circuits to generate an acoustic wave that propagates in only one direction along the substrate.,下面是Unidirectional surface wave transducers专利的具体信息内容。
