An example of a lenticular fabric sheet that changes from a blue background with white stars to a white background with red stars. A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. [1] When the surface of the fabric is smooth, it often has a reflective and light-distorting appearance.
Metamaterial cloaking is the usage of metamaterials in an invisibility cloak.This is accomplished by manipulating the paths traversed by light through a novel optical material.
Energy shield from the game Second Life. In speculative fiction, a force field, sometimes known as an energy shield, force shield, energy bubble, or deflector shield, is a barrier produced by something like energy, negative energy, dark energy, electromagnetic fields, gravitational fields, electric fields, quantum fields, telekinetic fields, plasma, particles, radiation, solid light, magic, or ...
"It's like an invisibility cloak but with the exception that we are splitting the object, the visual silhouette, into smaller bits," Hart said. The study's authors released a video showing some of ...
A Berkeley Lab press release notes, "In the...study when red light struck an arbitrarily shaped 3D sample object measuring approximately 1,300 square microns in area that was conformally wrapped ...
The flights would not begin until research into production and maintenance of these bubbles is completed, which the authors estimate would require a minimum of 10–15 years. After that, the space shield may be large enough by 2050 to prevent crossing of the 2 °C (3.6 °F) threshold. [21] [20] [22]
The temperature differences between the hot and cold sides of the James Webb Space Telescope five-layer sunshield. The sunshield acts as large parasol allowing the main mirror, optics, and instruments to passively cool to 40 kelvins (−233 °C; −388 °F) or cooler, [6] and is one of the enabling technologies that will allow the JWST to operate. [10]
A lenticular lens is an array of lenses, designed so that when viewed from slightly different angles, different parts of the image underneath are shown. [ 1 ] [ 2 ] [ failed verification – see discussion ] The most common example is the lenses used in lenticular printing , where the technology is used to give an illusion of depth, or to make ...
