    • WPT technology Transmission distance Energy attenuation Conversion efficiency Key limitations
      Electromagnetic induction 0–10 cm > 90% 85%–95% Ultra-short distance, high flux leakage
      Magnetic resonance coupling 0.1–5 m 50%–80% 60%–80% Sensitive to alignment, environmental interference
      Microwave/radiowave 1–100 km > 99% < 10% Low efficiency, electromagnetic interference
      Single-Wire Power Transmission (SWPT) 50 m–1 km 5%–15% 80%–95% Dependence on single-wire medium, limited theoretical validation
