Research on Electromagnetic Characteristics of Metamaterial based on FDTD Algorithm and Physical Model

The role of electromagnetic properties in the properties of meta materials is very important, but there is a problem of inaccurate evaluation of results. The light transformation theory cannot solve the problem of electromagnetic properties in the properties of meta materials, and the evaluation is unreasonable. Therefore, an FDTD algorithm and physical model is proposed for electromagnetic characteristic analysis. Firstly, the rotation equation theory is used to evaluate the meta material, and the index is divided according to the electromagnetic characteristics to reduce the electromagnetic characteristics in the interfering factor. Then, the rotation equation theory analyzes the electromagnetic characteristics, forms an electromagnetic characteristic scheme, and synthesizes the electromagnetic characteristics, results Analyses. MATLAB simulation shows that under certain evaluation criteria, FDTD algorithm and physical model for meta materials The accuracy of electromagnetic characteristics and the time of electromagnetic characteristics is better than the light transformation theory.
