Abstract (en)
[origin: WO2017089090A1] Disclosed is a transducer having fewer second-order nonlinearities. In order to reduce nonlinearities, the transducer (IDT) comprises an insulation zone (IB) between the electrode fingers (EFI1) and the opposite busbar (BB), and a dielectric material (DM) for reducing the electric field strength (Ey) in the insulation zone.
