Once the illumination and view angles are determined, LESS calculates the proportions of the four components within each pixel (red rectangle) using ray tracing and subsequently generates the ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

A photosensitizer (PS) is a chemical species that initiates a reaction upon absorption of light. Although the chemical compositions and practical applications of PS' differ widely, they all follow the ...
