Abstract
Method for focusing an electromagnetic or acoustic wave on a point near which one or more diffusers are placed, comprising a learning step in which the pulsed responses h(t) between the focus point and each antenna of the network are determined. Waves corresponding to signals S(t)=S(t)h(−t), where S(t) is a function of time and h(−t) is a temporal inversion of the pulsed response h(t), can then be transmitted form said antennas of the network.
