Recent Advances in RF Rectifying Technology for EM Energy Harvesting and Wireless Power Transfer

Dear Colleagues,

Radio frequency (RF) rectifying technology plays a vital role in electromagnetic (EM) energy harvesting and wireless power transfer applications. RF-to-DC conversion methods involve specialized circuits and components, such as diodes, resonant circuits, and impedance-matching networks. The antenna and rectifier circuit are essential components of an RF power harvesting system, enabling the conversion of RF power or alternating current (AC) into DC energy. Advancements in electromagnetic energy conversion techniques have paved the way for numerous applications, including wireless charging for electronic devices, energy harvesting for Internet of Things (IoT) sensors, and wireless power transfer for electric vehicles. These technologies offer the potential for increased convenience, mobility, and sustainability by eliminating the need for physical connections and enabling autonomous operation. Recent advancements in RF rectifying technology have opened up new possibilities and challenges in the field. This Special Issue aims to gather and showcase the latest research and breakthroughs in RF rectifying technology for EM energy harvesting and wireless power transfer.
