The dust particles are described as aggregates of a large number of constituent spheres of radius equal to 0.1渭m. We use a refractive index that is characterized by high values of its real and imaginary parts both increasing with wavelength. This refractive index reproduces the comet-Halley ...
The ABCD matrix is calculated in each slice and the trajectory of the ray was obtained. The method is demonstrated considering media with a refractive index distribution used to describe the human eye lens. The results are compared with the exact numerical solution for each particular distribution....
(9) has a core (10) of larger diameter than the core (4) of a downstream portion of fibre (2), both portions having cladding of lower refractive index than their respective cores, and a light detector (18) preferably linked by an index matcher (22) which surrounds a length of the ...
•An alternative method to calculate the paraxial ray path in a GRIN medium is presented.•The implementation of the method and the choice of the necessary parameters is easy.•The method works even with discontinuous refractive index distributions.•The method is tested with six different ...
We consider light scattering by uniform spheres of arbitrary size R and refractive index m. A new internal coupling parameter rho' = 2kR vertical bar(m(2) - 1)/(m(2) + 2)vertical bar where k = 2 pi/lambda and lambda is the wavelength is proposed that has a superior ability to ...

According to news reporting originating in Najran, SaudiArabia, by NewsRx journalists, research stated, "We proposed the numerical studies and machine learningprediction for the multilayered Borophene-GST-silica-Ag-based refractive index sensor for the 1.3-1.5 mum wavelength range. The top layers of...
When determining the chromatic dispersion parameters, the refractive index of doped silica glass is directly proportional to the concentration of the dopant [75]. A relatively large error characterizes the estimates of the parameters of modes obtained in this way; however, they fully satisfy the ...
