We demonstrate through simulations that traveling-Wave MRI is possible at lower B0 field strengths by lining the bore with metamaterials having negative permittivity close to zero. The metamaterial liner also dramatically increases spatial uniformity of the transverse fields and leaves ample clear bore for comfortable patient access with minimal additional risk of claustrophobia.
