Original Abstract

Utilizing negative permeability structures can increase magnetic coil range in magnetic resonance (MR) tomography. Negative e®ective permeability can be created by Split Ring Resonators (SRR). The resonator is constructed as a concentric metal ring with interspaces. These rings are deposited as regular matrix on dielectric substrate. It is possible to designQuasiPeriodic Resonators (QPR) for better homogeneity of the magnetic the ¯eld. QPR are composed from SRRs. The subject of this contribution is description of the design and measurement of QPR.
