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.
