Synopsis

A metamaterial arrangement that encloses a volume "metaBox" is shown to yield a significant and volume-homogeneous SNR enhancement in 3T MRI. Due to the integration of non-linear components, the structure self-detunes in Tx whilst being resonant in Rx. Fine-tuning capabilities are included in two different prototypes via (i) a manually trimmable capacitor and (ii) a Bluetooth-controlled digital capacitor that allows for a wireless interface. On-bench characterization as well as MRI experiments verify the functionality of the device. Thus, the metaBox is ideally suited for, e.g., imaging of extremities.
