On one hand resonant Wireless Power Transfer (WPT) can be realized by using resonant coils coupled via their magnetic fields; on the other hand Near-Field Magnetic Communications (NFMC) are currently receiving considerable attention for several possible applications. We present a novel structure that can be used for both WPT and NFMC; this structure shows a dual band transmission channel allowing...
Resonant Wireless Power Transfer (WPT) can be realized by using coils coupled via their magnetic fields; such systems can exhange energy in the mid-range. Information can also be exchanged via Near-Field Magnetic Communications (NFMC), which is currently receiving considerable attention for several possible applications. We present a structure that can be used for realizing both WPT and NFMC; this...
Electromagnetic Wireless Power Transmission (WPT) can be realized by using resonant coils coupled via their magnetic fields; in order to extend the range for power transmission, it is convenient to introduce additional relay elements. By considering a simple, yet rigorous, equivalent network, we derive a general property which is useful for the design of wireless power transfer networks with relay...
We present a novel resonator, based on a coaxial capacitor, suitable for resonant magnetic-coupled Wireless Power Transfer (WPT) applications. Its advantages are compactness, ease of manufacture and low cost. In our structure, the electric field is primarily confined inside the coaxial cable, while the magnetic field is generated by the currents flowing on the outside conductors. The paper describes...
Electromagnetic Wireless Power Transmission (WREL) can be achieved by using resonant coils coupled via their magnetic fields; these resonant coils must be, in addition, properly coupled to the source and load. By using a simple, yet rigorous, equivalent network, we introduce a computer-aided design procedure to reach the maximum efficiency for a given value of the resonators quality factor and for...
