This book presents the first application of Metamaterial, in particular Electromagnetic Band Gap (EBG) structures, as an artificial ground planes in 7 Tesla Magnetic Resonance Imaging (MRI) Radio Frequency (RF) Coils (antennas). The objective is to overcome problems of the conventional metallic ground planes of such coils, including the anti-phase currents, and the propagation of surface waves. The proposed EBG ground planes increase the effectiveness of coils in creating RF magnetic flux density inside the patient or a phantom, which will further improve the image quality. This book...
