Fig. 1

The extremal function on a relative scale. The real part and the modulus of the extremal function h to the basic uncertainty principle $(c=1)$. In the drawings, the parameters are distance d in mm from the stapes $(x=\frac{d}{l}=\frac{d}{6.6})$ and frequency $f=\frac{\omega }{2\pi }$ in Hz. The extremal function is shown for a fixed frequency f as a function of the distance d (in mm) to the stapes. The parameters are: $\epsilon =2\pi$, $\alpha =-\pi$, $\beta =2\pi$, $\kappa =4$.
