The wavelength formula is a fundamental concept in physics, particularly in the study of waves and electromagnetic radiation. Whether you're dealing with visible light, radio waves or any other type ...

We can also use wavelengths to calculate refractive index. By substituting \(v_{1}=f\lambda _{1}\) and \(v_{2}=f\lambda _{2}\) into \(n=\frac{v_{1}}{v_{2}}\) then ...

(Nanowerk News) Materials scientists can produce sub-wavelength artificial structures (split rings, honeycomb shapes and many more) to interact with electromagnetic waves so that the propagation of ...

Abstract: We designed a highly sensitive refractive index sensor based on geometric phase metasurfaces. The unit of this sensor consists of eight rotated silver cubes, which are placed on a silicon ...

A refractive index of zero induces a wave vector with zero amplitude and undefined direction. Therefore, light propagating inside a zero-index medium does not accumulate any spatial phase advance, ...

Toyohashi University of Technology researchers in collaboration with Massachusetts Institute of Technology (MIT), have developed a new material capable of retaining high transmissivity after thermal ...

Abstract: The Vernier effect has been successfully applied to various fiber-optic sensors as a way to increase sensitivity. The harmonic Vernier effect (HVE) serves as an extension of the Vernier ...
