In this work, we figure out a characteristic frequency equation of the T-shaped and overhang-shaped cantilevers. We consider the overhang lengths and widths that change the resonant frequencies and mode shapes. The obtained results reveal the number of optimum values of the frequencies corresponding to the mode shapes. Furthermore, a semi-empirical formula for the coupling strength of cantilevers in an array is proposed. It shows a good agreement between the theoretical model and the values obtained in experiments by other studies.
