Figure 3
Simulation and analytical results for (a) M of the WPT system and (b) k of the WPT system. The radius of the Tx coil, R1 varies from 5 to 25 mm, while the spacing between the two coils, h is swept from 4 to 20 mm. Symbols and lines represent the simulation and analytical results, respectively. R2 = 5 mm, r1 = 0.287 mm, r2 = 0.04 mm, and fp = 30 MHz.
