Abstract:

Strict phase and amplitude control of electromagnetic waves promises significant applications but it still remains a critical challenge. We present a simple, lucid yet versatile stochastic optimization approach to reduce the side-lobe level (SLL) in the radiation pattern of a beam-steering metasurface. The proposed algorithm is capable of efficiently handling computationally expensive electromagnetic (EM) problems. The efficiency of this method has been validated with numerical simulation results, which shows quick and optimal convergence.
