A Design Method for Arbitrary Three-Dimensional Conformal Metasurfaces

We propose a design method for arbitrary three-dimensional conformal metasurfaces. Based on this method, we have designed three conformal metasurfaces operating in the millimeter-wave and terahertz frequency bands. Simulation results are satisfactory, validating the correctness of our proposed method. One of the designed conformal metasurfaces achieves a gain of over 19.1 dB and a relative bandwidth of 16.7%. The proposed design method is expected to have broad application prospects in the design of wearable devices.
