NEGATIVE VALUES. "The first terahertz metamaterials able to achieve a desired magnetic response, which included negative values for permeability, were passive materials. Because of this, "tuning" was achieved by fabricating a new material, with slightly altered dimensions to create a new response. However, the notable advance, or practical achievement, is actually demonstrating the manipulation of terahertz radiation with metamaterials.” https://en.m.wikipedia.org/wiki/Terahertz_metamaterials View in LinkedIn

THz AND METAMATERIALS. "Development of metamaterials has traversed the electromagnetic spectrum up to terahertz and infrared frequencies, but does not yet include the visible light spectrum. This is because, for example, it is easier to build a structure with larger fundamental elements that can control microwaves.” https://en.m.wikipedia.org/wiki/Terahertz_metamaterials View in LinkedIn

UNCLAIMED TERRITORY. "Terahertz frequencies, or submillimeter wavelengths, which exist between microwave frequencies and infrared wavelengths can be metaphorically termed "unclaimed territory" where almost no devices exist. Because there are limits to propagating the terahertz band through the atmosphere, the commercial sector has remained uninvolved with such technological development.” https://en.m.wikipedia.org/wiki/Terahertz_metamaterials View in LinkedIn

CHARGE SEPARATION. "A magnetic field has opposite polar ends, or charge separation. This is thought to be cause by different numbers of quarks and antiquarks with left- and right-handed helicity." https://lnkd.in/ePeWvpu View in LinkedIn

CHIRAL FLIPPING. "Our universe is full of magnetic fields, even in deep interstellar space. It has been hypothesized that this may be due to unequal numbers of left versus right chiral particles through a process called chiral flipping." https://lnkd.in/eBAYp9j View in LinkedIn

UNSEEN FORCES. “The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence.” (Nikola Tesla). https://lnkd.in/eyFtShi View in LinkedIn

DYNAMIC COMPOSITES. "Butterfly wings, like exoskeletons of most insects, represent a form of biological composite made of chitin fibers in a protein matrix. Similar to many other polysaccharide-based biopolymers, chitin is reported to be piezoelectric." http://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=1041&context=physicsgruverman View in LinkedIn
