One of the leading candidates proposed for enhancing efficiency has been called a technology metamaterials.""We performed a comprehensive analysis using computer models of wireless power systems
and found that MRFE could ultimately be five times more efficient than use of metamaterials and 50 times more efficient than transmitting through air alone,
"The researchers conducted an experiment that transmitted power through air alone, through a metamaterial, and through an MRFE made of the same quality material as the metamaterial.
The MRFE significantly outperformed both of the others. In addition, the MRFE is less than one-tenth the volume of metamaterial enhancers."

In the 1840s, physicist James Prescott Joule discovered that iron-based magnetic materials changed their shape but not their volume when placed in a magnetic field.
This phenomenon is referred to as"Joule Magnetostriction, "and since its discovery 175 years ago, all magnets have been characterized on this basis."We have discovered a new class of magnets,
""The response of these magnets differs fundamentally from that likely envisioned by Joule, "said Wuttig."

This produces a plasma consisting of carbon ions, which is deposited as a coating on the workpiece in the vacuum.

The interaction between liquid crystal molecules and plasmon waves on the nanostructured metallic surface played the key role in generating the polarization-independent
Energy trapped on the surface of the nanocube in this fashion is called a plasmon. The plasmon creates an intense electromagnetic field between the silver nanocube
and a thin sheet of gold placed a mere 20 atoms away. This field interacts with quantum dots--spheres of semiconducting material just six nanometers wide--that are sandwiched in between the nanocube and the gold.
The plasmon-trick For this sleight of hand the researchers led by Leuthold and his doctoral student Christian Haffner
the light is turned first into so-called surface-plasmon-polaritons. Plasmon-polaritons are a combination of electromagnetic fields
and electrons that propagate along a surface of a metal strip. At the end of the strip they are converted back to light once again.
The advantage of this detour is that plasmon-polaritons can be confined in a much smaller space than the light they originated from.
but rather plasmon-polaritons that are sent through an interferometer that is only half a micrometer wide.
and hence the velocity of the plasmons in one arm of the interferometer can be varied,
After that, the plasmons are reconverted into light, which is fed into a fibre optic cable for further transmission.
and that thus modulates the plasmons inside the interferometer. As such a modulator is much smaller than conventional devices it consumes very little energy-only a few thousandth of Watts at a data transmission rate of 70 Gigabits per second.
a quality found normally in metals and new"metamaterials, "which contain features, patterns or elements that enable unprecedented control of light by harnessing clouds of electrons called surface plasmons.
Unlike natural materials, metamaterials are able to reduce the index of refraction to less than one or less than zero.
Refraction occurs as electromagnetic waves including light, bend when passing from one material into another. Each material has its own refraction index,

The researchers created a scaled-down template of the athletic logo and drilled out tiny perforations on the top layer of the metamaterial structure.
Novel method for controlling plasma rotation confirmed Such a method could prove important for future facilities like ITER,
Rotation can stabilize instabilities in plasma, and sheared rotation--the difference in velocities between two bands of rotating plasma--can suppress plasma turbulence,
making it possible to maintain the gas's high temperature with less power and reduced operating costs.
Today's tokamaks produce rotation mainly by heating the plasma with neutral beams which cause it to spin.
however, rotating particles that leak from the edge of the plasma accelerate the plasma in the opposite direction,
Stoltzfus-Dueck and his team influenced intrinsic rotation by moving the so-called X-point--the dividing point between magnetically confined plasma
and plasma that has leaked from confinement--on the Tokamak à Configuration Variable (TCV) in Lausanne, Switzerland.
The experiments marked the first time that researchers had moved the X-point horizontally to study plasma rotation.
The results confirmed calculations that Stoltzfus-Dueck had published in a 2012 paper showing that moving the X-point would cause the confined plasma to either halt its intrinsic rotation
but modified rotation within the superhot core of the plasma where fusion reactions occur. The results indicate that scientists can use the X-point as a"control knob"to adjust the inner workings of fusion plasmas,
much like changing the settings on itunes or a stereo lets one explore the behavior of music.

despite the fiery sheaths of superhot plasma around them, researchers say. The technology might also help keep communication lines open to other hypersonic vehicles,
This so-called"plasma sheath"acts as a mirror against electromagnetic signals under most conditions cutting off radio communications with anything outside the vehicle.
because sharp-nosed vehicles have thinner plasma sheaths than blunt-nosed ones. But sometimes, blunt-nosed bodies are preferable
Other approaches involve using magnetic fields to control the plasma sheath or injecting water or other liquids into the plasma sheath to make it more permeable to radio signals,
but these methods require extra power and weight, respectively. Now, Gao and his colleague Binhao Jiang, also of the Harbin Institute of technology, reveal they might be able to use the plasma sheath itself to enhance signals from antennas to maintain communications during hypersonic flight."
"We may have found a novel approach to solve the communication blackout problem, "Gao told Space. com. The researchers explained that,
In combination with the plasma sheath this"matched layer"would generate resonant conditions during hypersonic flight,
For the resonance to work, the thickness of this matched layer and the plasma sheath must be smaller than the wavelengths of the radio signals used for communication, the scientists noted.
The properties of the plasma sheath can vary during flight, complicating any efforts to generate resonance,
"We don't need to know exactly the properties of the plasma layer, but we need to know the ranges for these properties,
