The employment of epsilon-near-zero material (ENZM) has been demonstrated to be the key to cloak designs. Furthermore, methods
for designing such materials at any frequency have been discussed. It has been shown that an ENZM may be manufactured for
any wavelength where the real part of silver permittivity is negative. Depending on the frequency, the ENZM is a dielectric
matrix filled with silver inclusion or silver foam. The losses in the ENZM may be even smaller than the losses in silver at
the wavelength where real part of silver permittivity is equal to zero. 相似文献

[reaction: see text] The Bergman cyclization of benzannelated enediynes is highly sensitive to ortho substitution. This finding opens possibilities for the rational design of conformer-specific and pH-dependent DNA-cleaving agents. 相似文献

Focusing of electromagnetic radiation of a point source with a wavelength of 3 cm by flat negative-refraction lenses formed by a hexagonal structure of metal cylindrical rods was studied. The spatial distribution of microwave field of H polarization in the lens focal plane was recorded by a radiovisor screen which converts it into a visible image. The full width at half maximum of the focal spot distribution at optimum focusing did not exceed half the emission wavelength. 相似文献
