Claim 1:
2. The method of claim 1 further comprising:
establishing a target resonant frequency (f0) that is within the acceptable range of resonant frequencies, wherein the first desired resonant-frequency change is further based on the target resonant frequency;
determining a second desired resonant-frequency change for a second PMUT (502-M,1) of the plurality thereof, wherein the second desired resonant-frequency change is based on the acceptable range of resonant frequencies, the target resonant frequency, and the preliminary value (fn-M,1) for the second PMUT; and
imparting the second desired resonant-frequency change on the second PMUT by establishing a second profile of at least one of stiffness and mass along the first lateral dimension of the second membrane (204-M,1).
