Abstract
The invention compensates for abnormal operating temperatures and/or abnormal behaviors of a holographic metasurface antenna (HMA) that is generating a beam based on a holographic function. The HMA is characterized with different holographic functions for a plurality of operating temperatures and a plurality of behaviors during the manufacturing process. The characterization of the HMA identifies different hologram functions that cause the HMA to generate more or less heat or exhibit more or less abnormal behavior while generating equivalent beams. Further, or more characterizations of a hologram function may be performed remotely after the HMA is installed in a real world environment. An operating temperature and/or a temperature gradient may be detected by temperature sensors physically located on a circuit board for the HMA.
