Method of controlling the directivity and the polarization field distributions consistent in a medium reverberant.

摘要

The present invention relates to a method for generating and controlling a field distribution spatial and temporal - having a predefined characteristics such as one or several directions of propagation, a level of the intensity of the high field, and a polarization in an enclosure reverberation. For this purpose there are two different networks of the transducers of order to estimate a transfer function between the two networks and to determine the excitation signals using the technique of temporal reversal. The excitation signals make it possible to generate the field of spatial and temporal - according to the predefined characteristics.
