Abstract
AbstractThis letter presents a Rubik metamaterial with sextuple orbital angular momentum (OAM) capabilities. The design is based on a comprehensive algorithm that draws inspiration from the Rubik's cube. This metamaterial can generate multiple phased vortex waves using only one model and is easily constructed from metallic blocks with varying heights. The performance of the metamaterial is verified at 18 GHz with a gain of over 30 dB. A faster verification process is achieved using an automated program based on macroscript for height‐adjusted Rubik metamaterials, which is more efficient than manual operations. By calculating the purity of the sextuple OAMs, it can be determined that the Rubik model is capable of generating multiple phased vortex wave beams as effectively as possible. This Rubik metamaterial has potential applications in experimental and educational settings, particularly with the growing trend in three‐dimensional printing.
