Procedimiento y dispositivo de transmisión de ondas |
摘要 |
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 hij(t) between the focus point and each antenna of the network are determined. Waves corresponding to signals Sji(t)=Si(t)hij(−t), where Si(t) is a function of time and hij(−t) is a temporal inversion of the pulsed response hij(t), can then be transmitted form said antennas of the network. |
