WebAcoustic metamaterials or phononic crystals can be understood as the acoustic analog of photonic crystals: instead of electromagnetic waves (photons) propagating through a material with a periodically modified optical refractive index (resulting in a modified speed of light), the phononic crystal comprises pressure waves (phonons) propagating through … Web19 jan. 2024 · The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that the refractive index is the measure of the bending of a light ray when passing from one medium to another. Mathematically, it can be represented as a ratio between two different velocities – the ... اغاني 3
