Abstract

Disclosed are an interdigital resonator and a filter. The interdigital resonator includes a piezoelectric layer and an interdigital transducer located on one side of the piezoelectric layer. The electrode fingers include a double-layer electrode structure and at least one scattering structure provided in the double-layer electrode structure. The double-layer electrode structure includes at least two laminated electrode layers. The scattering structure includes scattering holes and scattering media provided in the scattering holes. The scattering holes penetrate through at least a part of the double-layer electrode structure. The acoustic impedance of the scattering medium is different from the acoustic impedance of an electrode layer where the scattering medium is located.
