Abstract
The effect of electromechanical cross-talk in high frequency (> 30 MHz) kerfless annular arrays is investigated. The high cross-talk across the array causes element broadening which increases the effective element width, and results in an increase in the pedestal secondary lobe level. The broadening limits how close to an array one can image. When the element broadening is taken into account by widening the electrode dimensions in an ideal array, the ideal radiation pattern agrees well with finite element model and experimental radiation patterns.
