Abstract

A metamaterial based microstrip loop element is proposed for the ultra-high magnetic field MRI body coils. The advantage of the leaky wave broadside radiation capability of the metamaterials is utilized. A 12 cm by 12 cm square loop simulated at 447 MHz for 10.5T demonstrates good penetration of magnetic field into the phantom with no change in the resonance condition or the Q-factor after loading. It also maintains the uniformity of the field inside the phantom over a large field of view. The proposed design verifies that a resonator coil element longer than half-wavelength can be designed without affecting magnetic field distribution using metamaterials.
