Phononic bandgaps in silicon plate with metallic pillars
نویسندگان
چکیده
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.

It is shown that it is possible to obtain complete planar phononic bandgaps in square and hexagonal (honeycomb) lattice phononic crystals formed by etching a periodic array of circular holes in a thin silicon plate (or membrane). Also, better bandgap properties are obtained using the hexagonal lattice structure; and, with practical structure sizes, it is possible-to-obtain a gap-to-midgap ratio...
