Web(Received 26 August 2011; accepted 15 November 2011; published online 5 December 2011) We present the numerical and experimental investigations of micromechanical resonators made by creating alternate defects with different central-hole radii (r0) in a two-dimensional (2-D) phononic crystal (PnC) slab. A phononic crystal is an artificial and periodic structure that supports the propagation of mechanical waves. By artificial, we refer to its technological fabrication process, by a human or a machine, at almost any available scale.
