Apparatuses and systems are provided for improving wireless power transmission for mobile devices. An enclosure for a mobile device may include a first electrical coil configured to establish a first wireless coupling with a transmitter coil of a power supply and a second electrical coil configured to establish a second wireless coupling with the first electrical coil and to establish a third wireless coupling with a receiver coil of a mobile device. A distance between the receiver coil and the transmitter coil may exceed a range over which the transmitter coil may be able to transfer power to the receiver coil via a single wireless coupling between the transmitter coil and the receiver coil. The first wireless coupling, the second wireless coupling, and the third wireless coupling, when established, may enable the transmitter coil to perform a wireless power transfer to the receiver coil.

A system for facilitating wireless energy transmissions. The system comprises a ground station and a space station. The ground station is positioned in a location on the earth. The ground station comprises a transmitter device. The space station is positioned in an orbit around the earth. The space station comprises a primary receiver device and a primary transmitter device. The primary receiver device comprises a receiver transceiver. The transmitter device transmits terahertz electromagnetic wave energy wirelessly to the receiver transceiver. The receiver transceiver receives the energy wirelessly from the transmitter. The receiver transceiver comprises a receiver enclosure comprised of a metamaterial. The receiver enclosure converts the terahertz electromagnetic wave energy into electrical energy based on the receiving. The receiver enclosure comprises a receiver antenna comprised of superconducting material and facilitates the receiving. The primary transmitter device transmits the electrical energy wirelessly to a secondary receiver device based on the converting.
