- Abstract
- The complex permittivity and permeability of various periodic metamaterial (MTM) cells are extracted by using a fictitious rectangular waveguide consisting of perfect electric conductor and perfect magnetic conductor walls. The shapes of the MTM cells include a thin wire (TW), a single split-ring resonator (SSRR), a double SRR (DSRR), a modified SRR, and a structure combining the TW and DSRR. The TW falls in the negative-epsilon/positive-mu region. the SRRs in the positive-epsilon/negative-mu region, and the combined structure in the negative-epsilon/negative-mu region. We also investigate how the permittivity and permeability, are affected by the dimension parameters of the MTM cells. Another extraction technique utilizing time domain signals is developed to overcome some limitations that the waveguide technique cannot handle. (C) 2009 Wiley Periodicals, Inc.
