Abstract : The electromagnetic analysis involved in magnetic resonance imaging scanners is becoming more challenging. The wavelength of the RF-pulse is continuously decreasing as the static magnetic field is increased, looking for an enhancement of the MRI performance. The scanners are getting more complex as they are now composed of multiple receiving and transmitting antennas. Furthermore, the inclusion of metamaterials and metasurfaces are nowadays under study, looking for an homogenization of the RF magnetic fields. Efficient and accurate electromagnetic tools for the analysis and design of complex High-Field and Ultra High-Field MRI antennas is required. In this work, an efficient analysis tool based on the method of moments and on the array scanning method is proposed. Fully representative designs are studied, and results are compared with commercial software.
