Abstract (en)
[origin: WO2016011227A1] Described embodiments include a system, apparatus, and method. An apparatus includes an array of at least two groups of at least two artificially structured electromagnetic unit cells. Each group of the at least two groups configured to be respectively linearly arranged with respect to the z-axis of the bore of MRI or NMR device. Each group of the at least two groups of artificially structured electromagnetic unit cells configured to transform an incident pulse of radiofrequency electromagnetic waves into a pulse of radiofrequency magnetic field B1 orientated transverse to a segment of the z-axis and spatially proximate to the group. The apparatus includes a radiofrequency electromagnetic wave conducting structure configured to selectably distribute a received pulse of radiofrequency electromagnetic waves to a group of the at least two groups.
