Abstract(in English) | The resonator consisting of a piezoelectric film on alternately laminated low and high acoustic impedance layers seems to be useful as a piezoelectric resonator for use in a very high frequency range from 500MHz to over ten GHz. This resonator is theoretically analysed using an equivalent circuit model taking account of acoustic loss and electrode thickness. It is shown that the Q approaches to that of the piezoelectric film with increasing layer number of multilayers. Even if the layer number is large enough, the admittance response disagrees with that of the piezoelectric film with traction-free surfaces and K_ |
