In this paper, the design and testing of several metamaterials (MTMs) that exhibit double negative medium properties at X-band frequencies are reported, and it is shown conclusively that the MTMs treated exhibit DNG properties in the frequency range of interest.Abstract:
The design and testing of several metamaterials (MTMs) that exhibit double negative (DNG) medium properties at X-band frequencies are reported. Double negative media are materials in which the permittivity and permeability are both negative. Simulation and experimental results are given that demonstrate the realization of DNG metamaterials matched to free-space. The extraction of the effective permittivity and permeability for these DNG metamaterials from reflection and transmission data is treated. It is shown conclusively that the metamaterials treated exhibit DNG properties in the frequency range of interest. The designed MTMs consist of combinations of capacitively loaded strip (CLS) and split ring resonator (SRR) inclusions in a background dielectric substrate. Applications for DNG media are in the fields of sensor and energy transmission technologies.read more

Live and Feeder Cattle Options Markets: Returns, Risk, and Volatility Forecasting
TL;DR: The authors examines returns from holding 30-and 90-day call and put positions, and the forecasting performance of implied volatility in the live and feeder cattle options markets Implied volatility is an upwardly biased and inefficient predictor of realized volatility, with bias most pronounced in live cattle.

Negative Refraction Makes a Perfect Lens
TL;DR: The authors' simulations show that a version of the lens operating at the frequency of visible light can be realized in the form of a thin slab of silver, which resolves objects only a few nanometers across.

Experimental Verification of a Negative Index of Refraction
TL;DR: These experiments directly confirm the predictions of Maxwell's equations that n is given by the negative square root ofɛ·μ for the frequencies where both the permittivity and the permeability are negative.

Magnetism from conductors and enhanced nonlinear phenomena
TL;DR: In this paper, it was shown that microstructures built from nonmagnetic conducting sheets exhibit an effective magnetic permeability /spl mu/sub eff/, which can be tuned to values not accessible in naturally occurring materials.
