1. 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, and
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, and wherein:
the first electrode fingers have a first spacing between the first electrode fingers;
the second electrode fingers have a second spacing between the second electrode fingers; and
the first electrode finger is spaced from the second electrode finger by a third spacing different from the first spacing and the second spacing.
