These two values are quite similar, since the refractive index of air is only very slightly above 1. For example, a vacuum wavelength of 1000 nm would be 999.7259 nm in standard air; there is a difference of about 0.03% (and more for much shorter wavelengths). In the case of air, ...
The rejection wavelength and bandwidth of the filter can be designed by adjusting the structure parameters. Additionally, the angle and polarization of the incidence and refractive index of the surrounding medium affect the performance of the filter....
Dispersive interferograms in the visible are calculated numerically in a simple way using the model of an ideal two-beam interferometer with the sample gas of complex refractive index 谩() in the fixed arm. Non-absorbing as well as artificially absorbing nitrogen (N2) is considered as a model ...
The convergence of wave packets propagating from around 60°E contributes to the development and continuance of the quasi‐barotropic Aleutian High, which is associated with the extension of negative extended refractive index (Ks) region. The extension of negative Ks region is related to the ...
where d is the grating period, n is the wavelength-dependent refractive index of the prism, 𝑛𝑘nk is the wavenumber dependent refractive index, and 𝜃𝑘θk is the diffracted angle of each wavenumber. 𝜃𝑖θi is the incident angle to the prism, which is related to the wavelength...
