Dear List member, In two-dimensional cochlear box models excited by a single tone having a frequency below the cutoff, there is a travelling wave, in which the liquid-particles move on closed approximately elliptical trajectories in x-z-planes. Now I have attempted to derive the liquid-particle trajectories in the standing evanescent wave which is predicted if the single-tone frequency is above the cutoff. A few days ago I sent a rough draft "Remarks on Evanescent Waves in a Passive Two-Dimensional Cochlear Model" to a few colleagues. Now I have written an improved file Evanesc08b.pdf (four pages). Please write off-list if you would like to receive this pdf-file. With best wishes, Reinhart Frosch. Reinhart Frosch, Dr. phil. nat., r. PSI and ETH Zurich, Sommerhaldenstr. 5B, CH-5200 Brugg.
