Relationships between the absorption effect of CPML and n, κout and σout a.
n = 5 in (a1)–(a5); b. n = 11 in (b1)–(b5); c. n = 17 in (c1)–(c5). 1: (a1)–(c1) are relative errors of Hz in the receiving coil at the moment of 0.0002 s; 2: (a2)–(c2) are average relative errors of Hz in the receiving coil during the period 0–0.0004 s; 3: (a3)–(c3) are average relative errors of Hz in the receiving coil during the period 0.0004–0.0008 s; 4: (a4)–(c4) are average energies of the inner electromagnetic field during the period 0.0004–0.0008 s; 5: (a5)–(c5) are optimal indices based on the preceding data. σ0 = 2.936 × 10−4S/m on the X axis.
