When I analyze the results for a simple RF coil placed approximately 10 cm from my sample, I look at the power balance result (sim4life 4.4). I am clear with the meaning of Dielectric loss and radiated power. However, I do not understand what are the lumped elements losses ?
Since in my case, these losses represent up to 80% of the power loss, it is quite annoying. All my lumped elements were modeled as simple lossless capacitors or inductors. Do anyone know where these losses come from ?
