Dimensional stargates created with Metamaterials in China

Well, just stumbled across this tidbit on Red Ice Creations, always an interesting stop on the tour of the internet. Seems the idea of ‘stargates’ or dimensional portals isn’t as far fetched as we might think! I still think is a lot more complicated that this process demands…after all, Harry Potter figured it out pretty quick, right?

Concept Described: First Tunable Electromagnetic Gateway

Entrance to platform nine and three-quarters at King’s Cross Station, used by Harry Potter on his way to school. New research describes the concept of a gateway that can block electromagnetic waves but that allows the passage of other entities, like a ‘hidden portal’.
While the researchers can’t promise delivery to a parallel universe or a school for wizards, books like Pullman’s Dark Materials and JK Rowling’s Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway.
The work is a further advance in the study of metamaterials, published in New Journal of Physics (co-owned by the Institute of Physics and German Physical Society).

In the research paper, the researchers from the Hong Kong University of Science and Technology and Fudan University in Shanghai describe the concept of a “a gateway that can block electromagnetic waves but that allows the passage of other entities” like a “‘hidden portal’ as mentioned in fictions.”

The gateway, which is now much closer to reality, uses transformation optics and an amplified scattering effect from an arrangement of ferrite materials called single-crystal yttrium-iron-garnet that force light and other forms of electromagnetic radiation in complicated directions to create a hidden portal.

Previous attempts at an electromagnetic gateway were hindered by their narrow bandwidth, only capturing a small range of visible light or other forms of electromagnetic radiation. This new configuration of metamaterials however can be manipulated to have optimum permittivity and permeability – able to insulate the electromagnetic field that encounters it with an appropriate magnetic reaction.

Because of the arrangement’s response to magnetic fields it also has the added advantage of being tunable and can therefore be switched on and off remotely.

Dr Huanyang Chen from the Physics Department at Hong Kong University of Science and Technology has commented, “In the frequency range in which the metamaterial possesses a negative refraction index, people standing outside the gateway would see something like a mirror. Whether it can block all visible light depends on whether one can make a metamaterial that has a negative refractive index from 300 to 800 nanometres.”

Metamaterials, the area of physics research behind the possible creation of a real Harry Potter-style invisibility cloak, are exotic composite materials constructed at the atomic (rather than the usual chemical) level to produce materials with properties beyond those which appear naturally.

So, examining the wikipedia definition of metamaterials brought me to this fascinating tidbit…did you know they have Invisibility Cloaks???

Main article: Cloaking device
Metamaterials are currently a basis for building a cloaking device. A possibility of a working invisibility cloak was demonstrated on October 19, 2006. According to the article, “A team led by scientists at Duke University’s Pratt School of Engineering has demonstrated the first working “invisibility cloak.” The cloak deflects microwave beams so they flow around a “hidden” object inside with little distortion, making it appear almost as if nothing were there at all.”[21] The associated report was published in the journal Science.[22]

Such a device typically involves surrounding the object to be cloaked with a shell which affects the passage of light near it. It was claimed that plasmons could be used to cancel out visible light or radiation coming from an object. This “plasmonic cover” would work by suppressing light scattering by resonating with illuminated light, which could render objects “nearly invisible to an observer.” The plasmonic screen would have to be tuned to the object being hidden, and would only suppress a specific wavelength—an object made invisible in red light would still be visible in multicolored daylight.[23]
