WitrynaIn this work, we present a simulation of a left-handed metamaterial using the finite-difference time-domain (FDTD) method in conjunction with perfectly matched layers (PMLs). First, we develop a PML to work … Witryna24 gru 2024 · View the article/chapter PDF and any associated supplements and figures for a period of 48 hours. ... microwave metamaterials, designed for the radio-frequency range of 8–12 GHz, are experimentally fabricated and devices with extreme dispersion profiles, an airfoil-shaped beam-steering device, and a broadband, broad-angle …
Subwavelength imaging with composite metamaterials - Optica
WitrynaMetamaterials provide a unique pathway to generate, guide, modulate and detect electromagnetic waves by having structural features that are significantly smaller than the operation wavelength. The development of metamaterials enables intriguing applications ranged from wavefront manipulation, imaging with sub-wavelength resolution, … WitrynaAfter reviewing the requirements, which have to be satisfied by a metamaterial-based subwavelength imaging system, a thin film lens is reported herein. The material of the lens is a composite of spherical Ag nanoparticles embedded in SiO2 host material. The image of the lens is calculated by solving Maxwell equations with the transfer matrix … fubo wont take my card
3D Labyrinthine-type Acoustical Metamaterial Proposals for …
WitrynaMetasurface is a recently developed nanophotonics concept to manipulate the properties of light by replacing conventional bulky optical components with ultrathin (more than 10 4 times thinner) flat optical components. Since the first demonstration of metasurfaces in 2011, they have attracted tremendous interest in the consumer optics and electronics … WitrynaIn terms of optical constants-a description that has been thus far lacking. From our theoretical approach, we construct a device that yields over 95% absorption in simulation. Our fabricated design consists of a planar single unit-cell layer of metamaterial and reaches an absorptivity of 77% at 1.145 THz. 展开 Witryna1 cze 2014 · Abstract.
