Abstract
Many techniques have been developed to improve magnitude and homogeneity of B1+ field at high field MRI. In order to manipulate B1+ field, we have designed one cell metamaterial (MM) plate. When proposed material was placed between RF transmit coil and phantom, B1+ magnitude and homogeneity significantly improved. Measured results show over 100 increase of B1+ magnitude in specific area in the case when box monopole antenna was used as a transmitter. When small loop antenna was used as a transmitter, there was zero B1+ field without MM plate and significant B1+ when MM plate was inserted.
