ABSTRACT
Dispersion curves employed for designing Love wave based liquid sensing devices may provide
more accurate information if due consideration is given to parameters describing microstruc-
tural behavior of the substrate. The present study involves mathematical modelling of Love
waves propagating in a hybrid structure consisting of an elastic layer in the middle overlying
a size dependent substrate, loaded with a viscous liquid (Newtonian) half space. Numerical
computations are carried out to graphically demonstrate the effects of various parameters:
characteristic length of the substrate, thickness of the elastic layer, viscosity and density of
the overlying viscous liquid (Newtonian) on dispersion characteristics.
