Abstract
An oscillator using high order Lamb wave modes is presented. Due to the multimode property of Lamb waves, high frequency oscillators using high order mode Lamb waves can be fabricated. To select the operating mode of the Lamb wave oscillator, a high order mode selector is inserted into the feedback loop. An oscillator using the 13th antisymmetric mode (a13) in Lamb wave is achieved in experiments and the oscillating frequency is 5.30 times higher than that of the a0 mode excited by the interdigital transducer.
