A woman wears sunglasses featuring a highly reflective optical coating Diagram of a dielectric mirror. Thin layers with a high refractive index n 1 are interleaved with thicker layers with a lower refractive index n 2. The path lengths l A and l B differ by exactly one wavelength, which leads to constructive interference.
Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...

A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
Bill Gates told Patrick Collison that younger generations should worry about four things. They are the climate crisis, unchecked AI, nuclear war, and the spread of disease.
Ellipsometry can probe the complex refractive index or dielectric function tensor, which gives access to fundamental physical parameters like those listed above. It is commonly used to characterize film thickness for single layers or complex multilayer stacks ranging from a few angstroms or tenths of a nanometer to several micrometers with an ...
