Theoretical Analysis of Elastic Sensitivity for Different Love Wave Propagation Modes

Abstract

A theoretical study about the elastic effect in a Love wave sensor with nanostructured guiding/sensitive layer was carried out. Two possible cases, for gas sensing applications, were taken into account; 1) the gas penetrates completely into nanostructured guiding layer (guiding monolayer), and 2) the gas interacts exclusively with the surface of the guiding layer (guiding bilayer). The results showed a differentiated sensitivity behavior of the sensors in both cases.
