First Time

Mie scattering theory has been widely used to solve the problem of light scattering by single spherical particles in many fields. In this article, it was applied for the development of opaque fiber for the first time. Firstly, the spheroid particles were simplified as equivalent spherical particles. Then, the extinction coefficient was calculated using the Matlab program and the influences of the size parameter, refractive index and the wavelength of the incident light on the extinction coefficient were discussed in detail. Finally, the results indicated that the extinction coefficient depended greatly on the dimension and the refractive index of the particles, and also the wavelength of the incident light. For the development of the opaque fiber, it would be better to choose particles that had the higher refractive index and a certain diameter distribution to achieve the most effective light scattering.

Abstract The scattering and absorption characteristics of light by spherical particles are often analysed based on the classical Mie scattering theory.In this paper，we study refractive index sensor of multi-mode based on the Mie scattering and its extension theories. Based on the Mie scattering theory, the light extinction, scattering, absorption cross-section, and absorption efficiency associated with the spherical particle can be calculated.The structure that we design has a long wavelength possesses a higher power than that with a short wavelength.Also,the structural parameters induces a red-shift in the resonance spectrum. Lastly,the results of multi-mode are obtained: the transmittance of modes 1, 2, and 3 vary within the ranges 0.43–0.67, 0.61–0.46, and 0.26–0.5, respectively; the figures of merit of modes 1, 2, and 3 can reach as high as 12, 27.7, and 3.8, respectively; the refractive index sensitivity can reach as high as and . As indicated by these findings, the proposed structure can significantly improve the transmission characteristics of nanodevices. Such a structure holds significant potential for application in the field of on-chip plasma sensing and optical communication.

Using the multiple scattering model of non-line-of-sight ultraviolet light to simulate and analyze the atmospheric channel characteristics in the complex environment of haze and dust. The Mie scattering theory and T matrix method are used to analyze the path loss of spherical particles and non-spherical particles with particle concentration at different communication distances. The results show that when the communication distance is less than 50 meters, the communication quality under severe haze is the best, and for long-distance communication, the path loss under severe haze increases almost proportionally. In the non-line-of-sight ultraviolet light communication link, the higher the concentration of dust particles, the better the communication quality of the non-line-of-sight ultraviolet light communication transmission. Analysis of the scattering coefficient of spherical particles is significantly greater than that of non-spherical particles.

Simple relations have been obtained, by numerical methods, between the diameter D of a spherical void (bubble) in a conducting medium of a given refractive index and the angular positions of the extrema of the Mie scattering intensities from the voids. The extrema are counted from the forward direction. These relations allow the determination of the positions of the extrema for a given diameter, or the reverse, without computational aids. The real part of the refractive index was varied from 1.25 to 15.00 and the imaginary part from 0.0 to 22.50. The size parameter α = πD/λ was varied in all cases from 4.00 to 24.00. The variable λ represents the wavelength of the incident radiation. These findings could thus be related to the scattering of microwaves by bubbles in water. Similar relations have also been obtained regarding the scattering of scalar waves by spherical voids. This corresponds to scattering of Schrödinger waves from complex spherical barrier potentials.
