In this paper, we use localized resonant phononic crystal as the unit cell to construct the acoustic negative refraction lens. Based on the vibration model of …
Witryna15 lis 2016 · Metamaterials are promising for a couple reasons. First, they enable the extreme miniaturization of existing optical devices. For example, we can take an eyeglass lens and we can make it 100 times thinner than a strand of hair. This allows us to translate traditionally bulky optical systems to extremely small form factors. Witryna1 gru 2015 · New optical materials called metamaterials have provided new ways to overcome diffraction limit in imaging by controlling the evanescent waves. Such …
Witryna4 kwi 2011 · Metamaterials have already been used to model various exotic optical spaces. Here we demonstrate that mapping of monochromatic extraordinary light distribution in a hyperbolic metamaterial along some spatial direction may model the flow of time. This idea is illustrated in experiments performed with plasmonic hyperbolic … http://www.cjors.cn/en/article/doi/10.12265/j.cjors.2024166
Witryna1 cze 2011 · Realizing subwavelength imaging with metamaterials was first suggested by Pendry , who rigorously proved that a slab of material with ɛ = μ = − 1 is a perfect lens with infinitely high resolution, and the loss would degrade the resolution to make the lens a super one , , .
