Abstract
An unapodized interdigital transducer apparatus, system, and associated methods. The apparatus includes a substrate, a pair of first electrodes oppositely positioned on the substrate, where an aperture is formed between the pair of first electrodes, and a plurality of variable length second electrodes arranged using a predetermined pattern defined by each second electrode in the plurality of second electrodes being coupled to one of the first electrodes in the pair of first electrodes and being configured to extend into the aperture. At least one second electrode in the plurality of second electrodes coupled to one of the first electrodes in the pair of first electrodes has the same length as at least another second electrode in the plurality of second electrodes coupled to another first electrode in the pair of first electrodes. A surface acoustic wave is generated upon application of electrical current to the pair of the first electrodes.
