Abstract 

In this report, we present a semi-empirical formula for the coupling strength of cantilevers in an array through a characteristic frequency equation of overhang-shaped cantilevers.  Based on the frequency equation, frequencies of a single cantilever (T or overhang shapes) can obtain. Furthermore, the results reveal the number of optimum values of the frequencies corresponding to the mode shapes with various shapes in a single cantilever. It shows a good agreement between the theoretical model and the values obtained in experiments by other studies.
