| Abstract: | The CSRR microstrip was simulated by the finite-difference time-domain(FDTD) method with the perfectly matched layer(PML) in this paper.The slow-wave characteristics of the CSRR microstrip were analyzed using the S-parameters gained from the FDTD method.The simulation results showed good agreement with that of the HFSS,which proved that the analysis method and the calculation in this paper were effective and correct.At the end of this paper,the influences of the CSRR dimensions on the stop-band characteristics were discussed in detail,the results of the analysis do have guiding significance in engineering design. |
