We investigated the dispersion characteristics of the propagation modes that progress on the tectorial membrane (TM). Recent studies have uncovered complex TM behavior and a possibility that TM might play an important role in the hearing system. An interaction between the TM and the fluid induces propagation modes, which are called TM modes. We found that there are several kinds of TM modes and analyzed the direction of the displacement of the TM that is caused by each mode. We also investigated the structural dependency of the angular wavenumber of each mode.
