Abstract

Passive ultrasonic filters have the potential to greatly improve nonlinear ultrasound measurement techniques. In this presentation, we designed, analyzed, and tested a phononic material with ultrasonic filtering properties. Finite element simulations show that the phononic material has a 2 MHz stop band. The structure’s behavior was verified with a simulated frequency sweep and will be experimentally validated on an additively manufactured phononic material.
