“…This indicates that the maximum transfer efficiency can be achieved only in the resonant state. Similarly, by taking the derivative of the transfer power P L with respect to the driving angular frequency ω, the optimization conditions based on maximizing the transfer power can be obtained as Equation (9), which indicates that the frequency splitting phenomenon appears [11]:…”

“…Normally, either coupled mode theory (CMT) [9][10][11][12][13][14][15][16][17] or circuit theory (CT) [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] can be used for analyzing SCMR. Transient analysis based on CT is sometimes more accurate than that based on CMT [18], thus CT is widely adopted.…”

“…This a favourable result as it offers the possibility of downsizing the dipoles whilst still achieving significant operating distances, relative to their size. Whilst there are practical challenges associated with achieving almost PEC-like behaviour, a number of examples exist in the literature where the results of this analysis have direct implications; for example, for WPT systems involving highly conducting materials such as graphene [28] or superconductors [29,30]. It is further worth noting that where this analysis is being used as the foundation to model more complicated geometries (such as coils or helical antennas for example), factors such as leakage inductance, parasitic capacitance and the proximity effect increasingly modify the behaviour of the system and should therefore be taken into account.…”

“…It is quite difficult to enhance system's transmitting range and efficiency by keeping the consistance of system electrical parameter. Many scholars have succeeded to certain degree in attempting to change the parameters of the resonator coils [12,13] by increasing the radius of the conductor or using multi-turn wire coils, etc. to improve the transfer efficiency but failed once the coils size parameters were fixed.…”
