Field-circuit co-simulation for microwave meta-materials with nonlinear components

摘要：

　　We demonstrate an analysis of the metamaterials medium consisting of SRRs (spilt ring resonators) integrated with nonlinear microwave components based on a circuit and 3D electromagnetic wave co-simulation method.The simulations are performed by using Wavenology EM, which is an efficient multiphysics and multiscale wave simulator.Our investigations show that the resonant frequency of the SRR loaded by a varactor reduces slightly when incident wave power increases,which is consistent with previous experimental research.We propose to connect an adjustable capacitor in parallel with the varactor to tune the resonant frequency.The simulation results indicate the tuning range is from 12.30 to 14.92 GHz, and the resonant frequency and quality factor decrease as the parallel capacitance increases.
