Method and apparatus for providing beam steering of terahertz electromagnetic waves
First Claim
1. A method for establishing a terahertz link, 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, that a detected terahertz signal of the detected terahertz signals is out of focus from a focus point;
applying, by the processor, a corrective signal to the respective beam steering device that corresponds to the detected terahertz signal that is out of focus from the focus point, wherein the corrective signal causes the detected terahertz signal that is out of focus from the focus point to be redirected;
measuring, by the processor, a signal-to-noise ratio of each of the detected terahertz signals; and
establishing, by the processor, the terahertz link via one of the detected terahertz signals with a highest signal-to-noise ratio.

Abstract
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.

19. A receiver, comprising:
-
a plurality of beam steering devices; a plurality of detectors, for receiving a plurality of terahertz signals, wherein one of the plurality of beam steering devices is arranged with a corresponding one of the plurality of detectors to form a respective combination, wherein a terahertz signal of the terahertz signals is received by the respective combination and is out of focus from a focus point, where a controller applies a corrective signal to a corresponding beam steering device that corresponds to the terahertz signal that is out of focus from the focus point, wherein the corrective signal causes the terahertz signal that is out of focus from the focus point to be redirected onto a respective detector of the plurality of detectors; and a processor for measuring a signal-to-noise ratio of each of the of terahertz signals and for establishing a terahertz link via one of the terahertz signals with a highest signal-to-noise ratio. - View Dependent Claims (20)
