1. A method for wireless power transmission with selective range to power a portable electronic device, comprising:

  • generating pocket-forming RF waves from a transmitter through an antenna connected to the transmitter;

    accumulating pockets of energy in regions of space in the form of constructive interference patterns of the generated RF waves;

    employing a selective range for charging or powering the electronic device in a predetermined variety of spots with the accumulated pockets of energy surrounded by null-spaces without accumulated pockets of energy; and

    implementing an adaptive power focusing to avoid obstacles interfering with the RF signals between the receiver and the transmitter for regulating two or more receivers providing charging or powering of the portable electronic device.
