Claim 0:
1. A micromachined ultrasonic transducer (MUT), comprising:
a first electrode, when seen in a top view, having first and second end portions along a first axis that extends in a longitudinal direction of the first electrode, the first end portion and the second end portion comprising semi-circular shapes each having a constant radius of curvature R,
wherein a second axis extends in a transverse direction perpendicular to the first axis and passes through a midpoint of the first electrode, the midpoint having a longitudinal location along the first axis, the first electrode being symmetric about both the first axis and the second axis and defining an outer perimeter having longitudinal edges that taper toward the midpoint such that the shape has a narrowest transverse width at the longitudinal location of the midpoint,
wherein a half-width of the first electrode is defined by a length L measured from the midpoint, along the second axis, to the outer perimeter of the first electrode,
wherein a total width of the first electrode at the narrowest transverse width is less than 2R such that the longitudinal edges of the first electrode on either side of the first axis at the first electrode's narrowest point has a concave shape, and
wherein R/L, is greater than 1.
