An energy-directing system having an energy-directing surface with a non-zero deflection angle

摘要

Non-zero deflection angles can be effective by implementing embodiments of the present disclosure to direct projected energy to a desired desired area, such as to an area closer to the energy directing surface. The energy-directing surface comprises an energy source and a four-dimensional coordinate system with two spatial coordinates based on the energy-directing surface and two angular coordinates based on the position of the energy source relative to the energy-directing surface, so that a propagation path is provided with a four-dimensional coordinate system. can be used together.
