Abstract
This paper presents and discusses a comparative numerical and experimental analysis of the electromagnetic (EM) phenomena arising in a laboratory phantom radiated by a radio-frequency field, simulating the exposure in a magnetic resonance imaging (MRI) context. A specific frequency-domain coupled finite element-boundary element solver, running in graphical processing unit environment, has been developed to analyze the EM effects as well in the presence of metallic objects simulating prosthetic implants. The experimental setup consists of an antenna radiating a cylindrical box filled with a tissue simulating liquid; a bulk metallic parallelepiped can be included to mimic the presence of a prosthesis.
