WIRELESS CHARGING WITH REFLECTORS
First Claim
1. A method for transmitting wireless power, comprising:
- generating two or more RF waves from a transmitter with at least two RF transmit antennas;
forming controlled constructive interference patterns from the generated RF waves;
accumulating energy or power in the form of constructive interference patterns from the RF waves to form pockets of energy;
converging the pockets of energy in 3-d space to a targeted electronic device;
redirecting the transmitted RF waves converging the pockets of energy in 3-d space to the targeted electronic device by a reflector for charging or operating the targeted electronic device with the pockets of energy.

Abstract
A wireless power transmission method may employ pocket forming in combination with one or more reflectors for redirecting the formation of pockets of energy towards one or more locations or electronic devices of interest. A transmitter can be purposely aimed at the reflector which can then redirect the transmitted RF waves towards a receiver embedded or operatively coupled to the electronic device. These reflectors can be installed in the room ceiling, walls, or floor, in relation to the position of the transmitter and the electronic device. Reflectors can be made of metallic materials capable of reflecting RF waves and can exhibit various configurations, shapes, sizes and surface textures, according to the application.
