    This paper proposes a wireless power transfer system for 3-D stacked multiple receivers. A 1:m selective power transfer system is realized by introducing a frequency/time division multiplexing system. Power transfer efficiencies at 6.78MHz and 13.56MHz are simulated to be 83% and 85%, respectively. Crosstalk and load transient performance is also compared with 1:1 system and confirmed that its degradation is not significant.
