Abstract
Official abstract text for this publication.
A surface acoustic wave resonator including an input interdigital transducer (IDT), an output IDT, and a pair of gratings with each being spaced from each other by a predetermined distance and attached to a substrate. In at least one embodiment, the distance is equal to one-half of the wavelength of the acoustic wave produced by the input IDT. In a further embodiment, the surface acoustic wave further includes a polymer layer and a biomedical coating covering at least a part of the polymer layer. The surface acoustic wave resonator has uses in the mass sensor and communications fields.
First claim
Opening claim text (preview).
We claim: 1. A surface acoustic wave resonator comprising: a substrate that is a 128° YX LiNbO 3 crystal; an input interdigital transducer mounted to said substrate, said input interdigital transducer having a plurality of electrode pairs; an output interdigital transducer spaced a distance L from said input interdigital transducer and mounted to said substrate, said output interdigital transducer having a plurality of electrode pairs; a first grating spaced the distance L…
