PROJECT TITLE :

Synthesized Magnetic Field Focusing Using a Current-Controlled Coil Array

ABSTRACT:

A completely unique synthesized magnetic field focusing (SMF) technology is proposed and nonradiative but centered magnetic field is experimentally demonstrated as a one-dimensional example. Contrary to common belief, a magnetic field can be targeted arbitrarily by increasing the quantity of current-controlled transmitting coils in an exceedingly manner the same as that of typical beam-forming. Moreover, the proposed SMF is freelance of frequency from dc to rf. Chronic issues related to standard wireless power transfer and magnetic induction tomography technologies, i.e., poor resolution and electromagnetic interference thanks to the extent of the magnetic field, can be resolved with the proposed SMF technology. The spatial resolution of the magnetic field of an experimental kit composed of 10 coils spaced five cm apart with a 90 cm long ferrite core was twelve.5 cm at a distance of 10 cm, that is 4 times that of a nonfocusing coil and which might be improved if a lot of coils are used.
