The proposed FDTD method for analysing nonlinear CRLH transmission lines significantly reduces the computational time consumption by about 82% compared to the conventional method, while maintaining good accuracy and numerical stability.
研究不足
The study is limited to the analysis of nonlinear CRLH transmission lines using the proposed FDTD method. The mathematical proof for the numerical stability of the proposed method is not rigorously proven due to the nonlinearity issue.
1：Experimental Design and Method Selection:
The study employs a new FDTD scheme for analysing nonlinear CRLH transmission lines. The method involves solving the equations for nonlinear CRLH transmission lines based on the FDTD method.
2：Sample Selection and Data Sources:
The proposed method is applied to a nonlinear CRLH transmission line as an example. The transmission line is composed of 20 unit cells with specific parameters.
3：List of Experimental Equipment and Materials:
The study uses Matlab R2014a (maci64) for coding and a 2 GHz Intel Core i7 processor for simulation.
4：Experimental Procedures and Operational Workflow:
The simulation is done for a period of 10 ns, and the number of iterations and the CPU execution time is calculated in each run.
5：Data Analysis Methods:
The results are compared with those of the conventional FDTD method to verify the accuracy and efficiency of the proposed method.
