Power output per unit resistance change $(\hat{r}=\mathrm{1)}$. (A) Frequency dependence of power output. The reduced frequency $\overline{\omega }$ is normalized by α ² + ζ. Power output $W(\overline{\omega })$ is normalized by $W_0=\gamma \zeta a^{2}n{i}_0^2\eta k^2\mathrm{/[2}\pi {(k+K)}^2{C}_0]$. Traces correspond to the values of ${\overline{\omega }}_{\eta }$: 1, (black); 2, (blue); and 3 (red). (B) Maximum power output plotted against ${\overline{\omega }}_{\eta }(={\omega }_{\eta }/{\omega }_r)$. The scale of power output is the same as in A. Traces correspond to the values of α ² + ζ: 1, (black); 1.5, (blue); and 2 (red).
