Abstract

The existence of phononic bandgaps is shown in a phononic crystal structure composed of a silicon plate with stubbed tungsten pillars. Using the finite element method for numerical simulations, the evolution of bandgap opening with varying design parameters is studied. Several bandgaps have been observed for different lattice symmetries. It has been shown that bandgaps of up to 40 gap to mid-gap ratio can be achieved for the triangular and square lattice.
