Abstract:
A method of creating a response in an object subjected to a user defined field distribution created by a wavefront generator wherein a distance and orientation between a transmitting array and the object are predetermined and the distance lies within a near field of the transmitter array, the method comprising:transmitting at a frequency at a first amplitude, a first phase and a first polarization from a first transmitter; transmitting at the frequency at a second amplitude, a second phase and a second polarization from second transmitter; transmitting at the frequency at a next amplitude, at a next phase and a next polarization from a next transmitter, wherein the first, second and next transmitters comprise the transmitter array; and determining an excitation vector comprising the amplitudes, phases and polarizations of the first, second and n transmitters using an optimization technique.
