Description

The static and dynamic Lorentz force detuning (LFD) derive from the sum of many mechanical modes and their interplay with EM radiation pressure. The LFD may give rise to instabilities in which the EM resonance frequency moves away from the “set point” value. The usual analytic theory for the oscillatory instability, and its threshold, are for a single, isolated mechanical mode; not a sum. We want a mathematical representation of the LFD spectrum that is compatible with an “isolated resonance” style of stability analysis, but nevertheless captures the phase-advance properties of a sum of many modes.
