Abstract :
Metamaterials are composite structures designed to produce the properties which are not available in nature and control electromagnetic waves in any desirable ways. A special class of wire metamaterials consists of periodic arrays of parallel conducting wires (the so-called wire medium), and they provide many opportunities to shape the form of electromagnetic field being especially promising for Magnetic Resonance Imaging (MRI) applications. In this work, we discuss how to efficiently use an annular wire metamaterial resonator in order to enhance and redistribute electromagnetic fields in 1.5 Tesla MRI.
