Multipole resonator

摘要

Three electrode pairs are formed on a monolithic piezoelectric element which exhibits anisotropic properties with respect to its X and Z axes. The electrodes of each pair are located on opposite sides of the piezoelectric element, with all electrodes being of predetermined dimensions. The first and second electrode pairs are aligned on the X axes at a predetermined spacing therebetween. The second and third electrode pair are aligned on the Z axis, also at a predetermined spacing.
