Figure 4.
Natural and resonant frequency color bar diagrams for the 2D linear system (6) (as in Fig. 2). A. Natural frequency fnat. B. Resonant frequency fres (same scale as A). Gray region and curves as in Fig. 2A2. C. Representative example of fres and fnat as a function of γ1 for γL = 1.5 (vertical dashed black lines in A and B). D. Representative example of fres and fnat as a function of γL for γ1 = 0.5 (horizontal dashed black lines in A and B).
