#Suntan reflector skin#

People who deliberately tan their skin by exposure to the sun engage in a passive recreational activity. It is most often a result of exposure to ultraviolet (UV) radiation from sunlight or from artificial sources, such as a tanning lamp found in indoor tanning beds. Recently published in Advanced Materials, the study was supported by the Samsung Research Funding Center and the National Research Foundation of Korea. Sun tanning or tanning is the process whereby skin color is darkened or tanned.

This study is also garnering attention from academic circles and industry for its applicability in precise semiconductor processes and high-resolution displays. Photographs show a woman using aluminum foil as a sun reflector for tanning her face the woman posed with wet. As it theoretically explains the ultrahigh refractive index of metamaterials that could not be explained in previous studies, the development of related research fields is anticipated in the future. The distributed Bragg reflector (DBR), which is made by stacking these metamaterials and polymer layers with a low refractive index, strongly reflected specific wavelengths.įurthermore, the research team established the theory of a plasmonic percolation model that can explain the extremely high refractive index. The 2D superstructures exhibited the highest-ever refractive index of 7.8 This material, which maximizes light-matter interaction, recorded the highest refractive index in the visible and near-infrared regions.

To overcome this issue, the research team developed a metamaterial that is uniformly arranged with the 1-nanometer-level gaps (nm, 1 billionth of a meter) by assembling spherical gold nanoparticles. This parabolic reflector combines the virtues of both vertical and horizontal reflectors into one exceptional unit. However, metamaterials with a high refractive index still have limitations from designing to manufacturing. Replaces popular Replacement shipping ship Hours Can 1000 or. Metamaterials - with properties that do not exist in nature - can be designed to have a negative (−) or ultrahigh refractive index. Fast Tanning - HO Rated Reflector Tan Reflector, of for America Sun Alaska T12 for 15 12- beds. A research team led by Professor Gi-Ra Yi (Department of Chemical Engineering) at POSTECH with the research team led by professors Seok Joon Kwon and Pil Jin Yoo (School of Chemical Engineering) at Sungkyunkwan University have together developed an ultrahigh refractive index metamaterial by closely packing gold nanospheres and a reflector that combines the metamaterial with a polymer.
