Extensive reference is also made to the study and application of what the tests called metamaterial*, including that some of this material: Can be used to "slow down light" and even "bring light to a complete standstill"
(Implying the ability to manipulate the speed of light (electromagnetic energy traveling at 186,000 miles per second)
May induce invisibility by manipulating refraction, reflectivity and increasing light absorption. The reports use terms like "optical isolation" and "transparency" and make reference to a "MetaMirror" technology
(Implying the ability to make something unable to be seen, and/or picked up by radar, scanning or imaging) Has the interesting ability to "compress electromagnetic energy" (Such condensing can make information and energy storage smaller and their transfer faster by reducing volume)
Exhibits a particular "tunable resonance" which was likely "determined during fabrication."
(The phrase "tunable resonance" refers to a vibration of large amplitude from a small stimulus. Very recent research shows potential in the field of "energy harvesting" technologies, or pulling energy from the environment for low-power electronic devices)
