Abstract
In MRI devices, the antennas used to generate the RF field are generally shielded from the rest of the device in order to limit the interference. A proper design of this shielding using metasurfaces is a promising way to improve the performances. In this paper, we propose a method to rapidly simulate metasurfaces whose behaviour is approximated using surface impedance boundary conditions. The method is based on the Method of Moments (MoM) and focuses on the rapid simulation of MRI devices for many different surface impedances, which is crucial for design and optimization. The results are validated using the CST commercial software.
