RADS, ASTHMA, COPD. "In healthy individuals, stimulation of sensory nerves may be protective; however, in individuals with airway disease, the heightened response to sensory irritants may exacerbate disease and have a deleterious health impact." https://lnkd.in/ey47aVM View in LinkedIn

"PHOTONIC HYPERCRYSTALS combine the features of metamaterials and photonic crystals within the same medium, offering new ways to control electromagnetic radiation." https://lnkd.in/e7BT7Dh View in LinkedIn

HYPERCRYSTALS. "Researchers at the University of Maryland, College Park (College Park, MD) and Towson University (Towson, MD) have combined the most interesting properties of photonic crystals and hyperbolic metamaterials into an entirely new material dubbed a hypercrystal." https://lnkd.in/ev_ZGjS View in LinkedIn

EITHER-OR. "Two technologies that have greatly contributed to our ability to control light are photonic crystals and metamaterials. Typically, these two types of photonic media are considered mutually exclusive." https://lnkd.in/e22HGsR View in LinkedIn

NEW FRONTIER. "The "photonic hypercrystal" is a photonic crystal made of a hyperbolic metamaterial. The structuring within the hyperbolic metamaterial has features about a hundred times smaller than the incident light's wavelength and twenty times smaller than the hypercrystal periodicity." https://lnkd.in/e22HGsR View in LinkedIn

GREAT PROGRESS. "Over the last few decades, considerable progress has been made in developing artificial optical materials with novel and often counterintuitive properties. Revolutionary research by Yablonovitch and John on photonic crystals was followed by the development of the electromagnetic metamaterial paradigm by Pendry." https://lnkd.in/ex6mxGb View in LinkedIn

BUILDING BLOCKS. "Metamaterials and photonic crystals currently represent the primary building blocks for novel nanophotonic devices." https://lnkd.in/eqM7z_U View in LinkedIn

PHONON LASERS. "A crystal that is “blind” to electromagnetic waves with wavelengths of about several hundred nanometres and “deaf” to sound at similar wavelengths within the crystal...The ability to make structures with both types of band gap could lead to breakthroughs in the field of acousto-optics." https://lnkd.in/ehwDYhR View in LinkedIn

"HYPERSONIC phononic crystals could also have a large impact in thermal management. Thermal energy in solids is transported primarily by electrons and phonons. The electronic contribution is important for materials with a large number of free carriers, such as metals. The presence of a phononic band gap would reduce the flow of phonons and therefore the thermal conductivity of a solid." https://lnkd.in/ehwDYhR View in LinkedIn

SOUND LENSES. "Negative refraction in phononic crystals is possible due to multiple scattering of sound waves at the solid–air interfaces. The development of superlenses for acoustic waves would be a major breakthrough for a variety of ultra-sound techniques." https://lnkd.in/ehwDYhR View in LinkedIn
