Vibration mode localization in coupled beam-shaped resonator array

Abstract

The use of vibration mode localization in arrays of mechanically-coupled, nearly identical beam-shaped resonators has been studied for ultra-sensitive mass detection and analyte identification. This study seeks to enhance the amount of amplitude change due to vibration mode localization with a beam shaped 3-resonator array. The preliminarily results have been discussed from view point of vibration characteristic by comparing experimental results with analytical ones, without a small mass perturbation.
