1. An electroacoustic resonator comprising:
a first busbar extending in a first direction;
a second busbar extending in the lateral direction;
a first plurality of electrode fingers coupled to the first busbar and extending in a second direction towards the second busbar without touching the second busbar, each of the first plurality of electrode fingers having a first end coupled to the first busbar and a second end, and each of the first plurality of electrode fingers extending a different distance toward the second busbar relative to adjacent electrode fingers of the first plurality of electrode fingers such that the second end of each of the first plurality of electrode fingers collectively form a first wave shape;
a second plurality of electrode fingers coupled to the second busbar and extending in a third direction toward the first busbar without touching the first busbar, each of the second plurality of electrode fingers having a first end coupled to the second busbar and a second end, and each of the second plurality of electrode fingers extending a different distance toward the first busbar relative to adjacent electrode fingers of the second plurality of electrode fingers such that the second end of each of the second plurality of electrode fingers collectively form a second wave shape, wherein the first plurality of electrode fingers and the second plurality of electrode fingers are interleaved;
a first plurality of gap reflectors substantially parallel to the first busbar, the first plurality of gap reflectors positioned between the first busbar and a curve associated with the second wave shape, wherein the first plurality of gap reflectors comprises a first group of at least one gap reflector having a first length in the first direction and a second group of at least one gap reflector having a second length different from the first length in the first direction; and
a second plurality of gap reflectors substantially parallel to the second busbar, the second plurality of gap reflectors positioned between the second busbar and a curve associated with the first wave shape, wherein the second plurality of gap reflectors comprises a third group of at least one gap reflector having the first length in the first direction and a fourth group of at least one gap reflector having the second length in the first direction.
