Abstract
Lamb wave devices were fabricated and tested to study parametric mixing through a nonlinear elastic modulus. A carrier wave was used to drive the time-variation of the elastic modulus in a traveling wave fashion. The signal wave is launched in the same direction as the carrier wave. The nonlinearity results in the signal to be mixed up and down with the carrier signal generating intermodulation terms. Through optimization, next generation RF components that are 5 orders in magnitude smaller than the current state of the art can be designed, freeing up real estate for larger batteries and additional sensors.
