1. A receiver, comprising:

  • a first antenna element for receiving wireless signals comprising energy resulting from constructive interference patterns of radio-frequency (RF) waves;

    a first rectifier, operatively coupled to the antenna element for converting the energy received by the first antenna element;

    a second antenna element for receiving wireless signals comprising energy resulting from constructive interference patterns of RF waves;

    a second rectifier, operatively coupled to the second antenna element for converting the energy received by the second antenna element;

    an input boost converter, operatively coupled to the first rectifier, the input boost converter being configured to step up the energy converted by the first rectifier and to determine at least one of (i) a global power maximum and (ii) a local power maximum produced in the first rectifier;

    a controller, operatively coupled to the input boost converter and the second rectifier, wherein the controller is configured todetermine available energy at the second rectifier,determine at least one maximum power point (MPP) value from the first rectifier, andtransmit an operational instruction to the first rectifier to further step up the energy converted by the first rectifier
