The growing interest of scientific community in the field of synthetic single/double negative materials has brought the effort to exploit their unique properties in various technical areas. One of the possible applications of these metamaterials is their utilization in subwavelength imaging. The recent work of some research teams deals with the application of single negative metamaterials with negative permeability for magnetic resonance imaging [1]. The concepts of the magnetoinductive lens have been proposed and realized [2]. The lens components are based on non-ferromagnetic materials. In spite of their insignificant response in the DC magnetic field, they exhibit magnetic response at certain resonant frequency. The resonant frequency approaches to the frequency of the excitation RF pulse [3]. By suitable configuration of the components the imaging effect can be observed and the device behaves like a magnetic lens. Most of the published papers describe the analysis of magnetoinductive lenses and the experiments in relatively low field medical MRI devices with the excitation frequency of tens of MHz [4]. This paper presents the design and development of magnetoinductive lens for application in the experimental mid-field MRI device which has a smaller field aperture and high resolution narrowband detection system.
