“…Energies 2022, 15, 4944 5 of 18 Kim et al (2017) showed that the Q factor for the circuit is the ratio of the energy in the energy-storing elements to the dissipation of the entire topology, multiplied by the angular frequency [11]. The relation equation for the Q factor is expressed as Q = ω × E stored P loss (11) According to Kim et al (2021) [4], the circuit Q factor for the series resonant circuit can be derived by…”

“…In addition, Q in Equation ( 20) represents the quality factor for the circuit of the entire system. According to a previous study [18], the definition for the quality factor of the system circuit is Equation (21). Differing from the Q S , the Q here represents the quality factor as far as the entire system is concerned, while Q S is only a quality factor for the coil on the Rx circuit.…”

“…|S 21 | in the lower band is greater than in the higher band. It might be because the current directions in L 1 and L 1 are the same in lower band, while they are reversal in higher band [16], which cause the field to increase in lower band and decrease in higher band. Though the measured |S 21 | is not good enough, 49.14% PTE at 6.78 MHz and 37.21% PTE at 13.56 MHz are obtained.…”
