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

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

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

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

"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

NEW MATERIAL. "Hypercrystals can be designed to exhibit a negative refractive index, without the negative magnetic permeability that is usually essential for such materials. In this way, it may be possible to use photonic hypercrystals for optical imaging, since a planar slab of such material can function as a Veselago lens." https://lnkd.in/e7BT7Dh View in LinkedIn

BANDGAPS. "Like a photonic crystal, the hypercrystals also have photonic bandgaps due to the fabrication process. https://lnkd.in/ev_ZGjS View in LinkedIn

HYPERCRYSTALS. "The magnetic field induces a periodic pattern of self-assembled stripes caused by phase separation into nanoparticle-rich and nanoparticle-poor phases, and the stripe periodicity is much smaller than the free-space wavelength in the hyperbolic frequency range, showing that the self-assembled optical medium is a photonic hypercrystal." https://lnkd.in/ev_ZGjS View in LinkedIn

FORBIDDEN GAPS. "Similar to photonic crystals, the hyperbolic dispersion law of extraordinary photons is modulated by forbidden gaps, frequency ranges where there are no photons, when the photon wavelength is close to the spatial period of the metamaterial. " https://lnkd.in/ex6mxGb View in LinkedIn
