| Abstract: | The S/sub 21/ spectra of microstrip ring resonators have been measured experimentally and also computed using the finite-difference time-domain (FDTD) method. The dielectric constant of the substrate was determined by fitting the simulation results to the experimental data. The results are more self-consistent than those obtained using the Wheeler-Hammerstad method. |
