## Abstract This paper shows how the dielectric constant of alumina and rutile substrates at microwave frequencies can be accurately determined by fitting the simulated __S__βparameter spectra of microstrip ring resonators, generated __via__ the finiteβdifference timeβdomain (FDTD) method, to exper
the boundary and the interior regions. Thus, it may be concluded that a chiral absorber provides an efficient and simple boundary termination for the FDTD method. ## Conclusions In this work, we have investigated the possibility of using a chiral absorber to terminate the grid in an FDTD scheme. T
