2011 JAN 12 - (VerticalNews.com) -- New research, 'Optimized reflector stacks forrnsolidly mounted bulk acoustic wave resonators,' is the subject of a report. "The quality factorrn(Q) of a solidly mounted bulk acoustic wave resonator (SMR) is limited by substrate losses,rnbecause the acoustic mirror is traditionally optimized to reflect longitudinal waves only. Wernpropose two different design approaches derived from optics to tailor the acoustic mirror forrneffective reflection of both longitudinal and shear waves," scientists writing in the journal IeeernTransactions On Ultrasonics, Ferroelectrics, and Frequency Control report.
