Wireless power beam device using microwave power transfer
2014 IEEE Wireless Power Transfer Conference, 2014The authors proposed a novel WPT system using ceramic dielectric resonators. Unloaded Q of ceramic resonator is several tens of thousands depending on the material. Thus, we can expect much longer transmission distance by using ceramic resonator. It was confirmed that the power transfer of this system was conducted by a combination both of coupling in ...

Wireless power transfer by focusing microwaves
Wireless power transfer (WPT) promises to revolutionize energy distribution. Electromagnetic waves propagate freely through space, and can be used for long distances. It is advantageous to use microwaves since its wavelength reduces the size of the necessary components, while avoiding absorption losses in most media.openaire +1 more source
