Analysis of frequency-controlled beam scanning based on holographic metasurface

The behavior of frequency-controlled beam scanning based on holographic metasurface, for instance, the scanning accuracy and sensitivity of frequency, has been substantially investigated. An immediate consequence of this work is that we provide a more general guideline of designing holographic metasurface with more flexible features, such as, multi-beam scanning, etc. A selected number of simulation results, calculated by performing the commercial software package of CST Microwave Studio, are presented to verify the proposed theory.
