Abstract: A radiofrequency (RF) resonator array device for use in magnetic resonance imaging (MRT), The RF resonator array device includes a substrate. An army of coupled split ring resonators are located on the substrate. Each of the coupled split ring resonators includes a first split ring resonator positioned on a first side of the substrate and a second split ring resonator positioned on a second side of the substrate located opposite the first side. The second split ring resonator is inductively coupled to the first split ring resonator. Methods of making and using the RF resonator device are also disclosed.
