Abstract:
We are designing a 1-bit reconfigurable unit cell capable of enabling beam steering of circularly polarized (CP) reflected waves when a linearly polarized (LP) plane wave is incident on it. The unit cell is designed to support 1-bit coding (”bit-0” and ”bit-1”) for both v- and u-polarized reflected waves by applying two distinct reverse bias voltages (3 V and 20 V) to varactor diodes. To optimize the design, we systematically vary key parameters of the unit cell using CST and collect data on its performance. This data will then be used to train a deep learning algorithm, allowing us to identify the most effective and efficient unit cell design for achieving optimal beam steering.
