Meta-surface can realize electromagnetic wave-front control, and has many possible applications. Due to the restriction of computational capacity, the full-wave simulation of this new technique becomes a big challenge, and it affects the further promotion of this structure. This project is based on the previous research works of the applicant, and it aims to develop a highly efficient electromagnetic simulation tool for the proposed meta-surface design. This project includes the following research topics: the analysis of multi-layered problem, fast integral equation solver, meta-surface based acceleration method. The applicant intends to design this simulation tool using the following new techniques: interpolation method based on Green's functions for multi-layered media, RBF-QR method, non-uniform interpolation point distribution, hybrid 2D/3D interpolation, cross-level translation and so on. The implementation of this project will not only contribute to the design and promotion of the proposed new structure, but also provide reliable ideas for simulation tools of other applications, and it is of great scientific significance.
