Claim 25:
26. An electroacoustic device, comprising:
a piezoelectric material;
a first electrode structure disposed above the piezoelectric material, the first electrode structure comprising first electrode fingers arranged within an active region having a first region and a second region, wherein:
at least one of the first electrode fingers has at least one of a different width or a different height in the first region than in the second region; and
the first electrode fingers comprise a first electrode finger that has 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,

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

the active region comprises a third region;
the first region is disposed between the second region and the third region;
the at least one of the first electrode fingers has at least one of a different width or a different height in the first region than in the third region; and
the at least one of the second electrode fingers has at least one of a different width or a different height in the first region than in the third region; and
a third electrode finger arranged adjacent to the first electrode finger or the second electrode finger, wherein the third electrode finger has a width or height in at least one of the second region or the third region that is less than a corresponding width or height of another electrode finger in the second region or the third region.
