← ScienceWhich risk increases for high-frequency resonant inductive wireless power transfer when impedance is mismatched?
A)Reflected wave power increases drastically✓
B)Skin effect losses diminish rapidly
C)Magnetic field density fully collapses
D)Antenna's radiation resistance totally vanishes
💡 Explanation
Impedance mismatch induces a reflected wave, because standing wave ratio increases, therefore reducing power transmission efficiency, rather than reducing conductive or radiation losses; the device suffers more harm under higher frequency.
