Microwave Beamforming for Non-Invasive Brain Stimulation

In this work, a microwave beamforming technique to stimulate deep brain area is presented. The proposed system is evaluated by a near realistic scenario with a 3D brain phantom model. Focusing the electromagnetic power by Time reversal space-frequency DORT is the key factor in this work. Simulation results show the satisfactory performance of the focusing and penetrating microwave signal to stimulating the nerve fiber in the deep brain area.
