Original Abstract Submitted
An acoustic wave device includes a piezoelectric layer and an interdigital electrode structure over the piezoelectric layer. The interdigital electrode structure includes a plurality of first electrode fingers extending from a first busbar towards a first apodization edge, and a plurality of second electrode fingers extending from a second busbar towards a second apodization edge. The plurality of first electrode fingers and the plurality of second electrode fingers are interleaved with one another. At least one of the first apodization edge or the second apodization edge follows a periodic arccosine apodization function over at least two adjacent electrode fingers. A number of periods of the first apodization edge or the second apodization edge is at least 2. A first distance between one of a first electrode finger or a second electrode finger and the respective periodic arccosine apodization function is less than or equal to a predetermined percentage of an apodization amplitude.
