Senyurek, V., Tansel, I., Unal, M., Baghalian, A., & Tashakori, S. (2019). Implementation of Heterodyne Effect in SHM and Talking SHM Systems. US patent office.

Systems and methods for implementation of the heterodyne effect in structural health monitoring (SHM) systems are provided. A system or method can include propagating a first signal with a first frequency and a second signal with a second frequency through a subject structure, and analyzing the output response to determine if a third frequency has been created, according to the heterodyne effect.
