Design of a hemispherical antenna array for magnetic field control in the brain
A hemispherical antenna array consisting of 42 elements operating at a frequency of 1.8 GHz was proposed and simulated. The array elements are distributed on a hemisphere to be placed on a human's head. By considering the problem as a boundary valued problem and finding the electric and magnetic field inside the brain, a beamforming technique was used that made use of the orthogonality property of the transverse electric and transverse magnetic fields in producing a delta like function beampattern in order to direct the magnetic field to the area of interest within the brain to cause magnetic deep brain stimulation.
