Project 2: Topological Acoustic (TA) Wave Radio Requency (RF) Devices

Project 2 addresses the design and implementation of acoustic wave (AW) radio frequency (RF) devices (e.g., surface AW or SAW and Bulk AW (BAW) devices) with topologically protected acoustic waves against backscattering (backscattering-immune TA waves). The objective is to reduce insertion loss (i.e., power consumption) and develop strategies to increase the functionality of these devices beyond passive filtering as well as enable reconfigurability of the devices. 

Therefore, for the impactful integration and miniaturization of TA concepts into telecommunication products, we must break a materials/device microfabrication barrier. New Frontiers of Sound (NewFoS) will focus on the use of low-cost, industry-accepted constitutive materials with the elastic contrast, ease-of-patterning, and possible reconfigurability to produce the TA components with the desired transmission and functionality. High-throughput, low cost, industry accepted fabrication methods will also be developed and employed.
