International Ultrasonics Symposium
At the International Ultrasonics Symposium in Florida, Sumy Jose has presented her two latest findings on BAW reflector stacks. In cooperation with researchers from NXP Semiconductors, Sumy and her supervisor Ray Hueting have developed three theoretical approaches for the optimization of Bragg-type BAW reflectors. Sumy presented the experimental verification of two of these approaches which was performed in collaboration with an external company. In addition, she also presented a rule of thumb for influencing the dispersion behavior of the stacks important for the spurious mode suppression.
