“…In each case, the effective real (" eff ) and imaginary parts (" 00 eff ) of permittivity are calculated at 2 GHz, by a modified transmission/reflection matrix method (TMM) using the values of complex S-parameters calculated by the FDTD method. 14,15) The calculated " eff and " 00 eff values were approximately constant up to the vicinity of resonance frequency.…”

We derive an improved prescription for the merging of matrix elements with parton showers, extending the CKKW approach. A flavour-dependent phase space separation criterion is proposed. We show that this new method preserves the logarithmic accuracy of the shower, and that the original proposal can be derived from it. One of the main requirements for the method is a truncated shower algorithm. We outline the corresponding Monte Carlo procedures and apply the new prescription to QCD jet production in e + e − collisions and Drell-Yan lepton pair production. Explicit colour information from matrix elements obtained through colour sampling is incorporated in the merging and the influence of different prescriptions to assign colours in the large N C limit is studied. We assess the systematic uncertainties of the new method.

“…The transmission properties of SRR's and wires have been thoroughly studied [13,16,17,18,19,20,21,22]. The physical shapes of SRR's have expanded to include: double slit tetragonal resonators [23], microstrip resonators [23], single, double, and quad multigap split ring resonators [24,25], pairs of short wires [18], S shaped and omega shaped resonators [26], double bars [27], dog bones [28], and complementary structures [29]. The effect of SRR positioning and cavities vs. free space has been studied as well as intercavity systems [30].…”

A metallodielectric metamaterial have been investigated by using FDTD (Finite Difference Time Domain) method and fabricated with a resin based rapid prototyping machine. It was composed of 7 layers of parallel periodic copper wires embedded in resin. The metallodielectric metamaterial shows a different near field distribution with direction of incident electric field E that causes different electromagnetic (EM) properties. In particular, when incident electric field E is vertical to the wires inside resin, we observe enhacement of electric field in the vicinity of the embedded metal wires according to the incident direction of electirc field E as compared with dielectirc wihout metal wires. The enhanced electric field by the embedded metal wire is responsible for the enhancement of effective dielectric constant.
