Wireless Power Transfer Efficiency Formula Applicable in Near and Far Fields
Microwave-based wireless power transfer in the near field (up to about 10 m) is now drawing much interest since the transfer range when using current magnetic induction or magnetic resonance methods is limited in current industry. The Friis efficiency formula is valid only in the far field, so this...
