Abstract

The method and apparatus in one embodiment may have: providing a two-dimensional axisymmetric oscillator having a beam containing two principal elastic axes and two principal damping axes; driving the beam with drive components to oscillate across corners of the beam at approximately 45 degrees to sides of the beam, the drive components having forcer components that provide drive and pickoff components that provide feedback; and oscillating the beam in a normal mode and a reverse mode.
