Zusammenfassung:	A method for wirelessly charging, by a transmitter, at least one receiver placed above at least one coil having at least one section, the method comprising: determining a plurality of charging locations that form a charging area above the at least one coil; determining a matrix of magnetic field contributions of each section in the at least one coil to each charging location of the plurality of charging locations; determining a magnetic field pattern of the charging area; calculating a current vector that comprises a current value for the each section in the at least one coil; and driving, by the transmitter, the each section in the at least one coil with the current vector for shaping the magnetic field pattern.
