<p>The device has acoustic paths (V1, V2) comprising input transducers (Te1, Te2) and output transducers (Ts1, Ts2) respectively connected to input ports (P1, P2) and an output port (Ps), and floating transducers (Tf1, Tf2) connected to an internal floating port (Pf). The input and output transducers are separated by distance equal to a specific formula comprising integer and propagation wavelength. The input and floating transducers are separated by distance equal to a specific formula comprising integer and wavelength. Each output transducer is connected to the same output port. The transducers are surface wave, plate wave and interface wave transducers.</p> |
