Abstract: | The nonlinear interaction between two bulk elastic waves of different polarisations is used to generate a propagating elastic wave carrying a correlation of the two input waveforms. Measurements show the high efficiency and dynamic range of the device and a variable-delay capability is demonstrated. |
