WebJul 8, 2024 · Refractive index (RI) is an inherent property of materials. It is very important to identify different substances through the detection of RI in many fields, such as biological sensing [ 1, 2, 3 ], agriculture, food industry and other fields [ 4, 5 ]. WebReflection at a dielectric boundary An electromagnetic wave of real (positive) frequency can be written (1210) (1211) The wave-vector, , indicates the direction of propagation of the wave, and also its phase-velocity, , via (1212) Since the wave is transverse in nature, we must have . Finally, the familiar Maxwell equation (1213)

WebThe phase velocity of an electromagnetic wave (such as light) in vacuum is a constant independent of frequency: In optics, it is more common to use the refractive index rather than the relative permittivity, which for nonmagnetic materials may be defined as.
