Assessment of a PML Boundary Condition for Simulating an MRI Radio Frequency Coil

Figure 2

The schematic view of the computational domain. (a) Longitudinal plane ( -plane in Figure 1(b)). (b) Transverse plane ( -plane in Figure 1(b)). “D” homogenous region of -field (shaded); “p”: the thickness of the PML; “s”: the distance from PML to the closest point on the coil geometry; “ ”: the diameter of the coil; “ ”: the length of the coil; “dh”: the diameter of region D; “lh”: the length of region D. The dark solid rectangle and circle denote the outline of the coil in the longitudinal plane and transverse plane, respectively.
