en Influence of Temperature, Geometry and Density of Nanoparticles on Composite Cladding Fiber تخصصی Special پژوهشي Research <p><span style="line-height: 20.8px;">&nbsp;In this paper, composite cladding optical fiber is used. Assuming that the emission of electromagnetic waves in the waveguide occurs by total reflection rule, negative Goos-Hanchen shift in the optical fiber for different forms of nanoparticles of different wavelengths and temperature simulated by MATLAB software. As a result, prolate ellipsoid nanoparticles are drawn with the least penetration depth. So the impact of changes in the density of nanoparticles in negative and positive Goos-Hanchen shifts as well as changes in the density of nanoparticles as a selected sample have been investigated per P and S polarized wavelengths. Finally, the dispersion curves and cut-off frequency of the composite cladding optical fiber has been described and it has been found that by changing the density of nanoparticles cut-off frequency mode can be controlled.</span></p> <p><span style="line-height: 20.8px;">&nbsp;In this paper, composite cladding optical fiber is used.
