METHOD AND APPARATUS FOR PROVIDING BEAM STEERING OF TERAHERTZ ELECTROMAGNETIC WAVES

摘要

A method and apparatus for establishing a terahertz link using a multi-element lens array that comprises a plurality of active beam steering device are disclosed. For example, the method receives detected terahertz signals from one or more detectors, where an active beam steering device is deployed with each of the one or more detectors, and determines, for each of the detected signals, if the detected signal is out of focus from a focus point. The method applies a corrective signal to each active beam steering device that corresponds to a detected terahertz signal that is out of focus from the focus point, wherein the corrective signal causes the detected signal to be redirected, and measures a signal-to-noise ratio of the detected signals. The method then establishes the terahertz link via at least one of the detected terahertz signals with a highest signal-to-noise ratio.

1. A method for establishing a terahertz link, the method comprising:
receiving, by a processor, detected terahertz signals from a plurality of detectors, where a respective beam steering device is deployed with each of the plurality of detectors; determining, by the processor, for each of the detected terahertz signals whether each of the detected terahertz signals is out of focus from a focus point or in focus from the focus point; measuring, by the processor, a signal-to-noise ratio of each of the detected terahertz signals that is determined to be in focus from the focus point; and establishing, by the processor, the terahertz link via one of the detected terahertz signals that is determined to be in focus from the focus point with a highest signal-to-noise ratio.
