Claim 19:
20. A method of fabricating an electroacoustic device, comprising:
forming a first electrode structure above a piezoelectric material, wherein forming the first electrode structure comprises forming first electrode fingers arranged within an active region having a first region and a second region, wherein forming the first electrode fingers comprises:
forming at least one of the first electrode fingers with at least one of a different width or a different height in the first region than in the second region; and
forming a first electrode finger having a width or height in the second region that is less than a corresponding width or height of the at least one of the first electrode fingers in the second region; and

forming a second electrode structure above the piezoelectric material and adjacent to the first electrode structure, wherein forming the second electrode structure comprises forming second electrode fingers arranged within the active region, wherein forming the second electrode fingers comprises:
forming at least one of the second electrode fingers with at least one of a different width or a different height in the first region than in the second region; and
forming a second electrode finger adjacent to the first electrode finger of the first electrode structure, wherein:

the first electrode fingers are formed to have a first spacing between the first electrode fingers;
the second electrode fingers are formed to have a second spacing between the second electrode fingers; and
the first electrode finger is formed to be spaced from the second electrode finger by a third spacing different from the first spacing and the second spacing.
