Dynamics of Motion of a Dielectric Nanoparticle Along the Interface of Media Under the Influence of the Force of Light Pressure Generated by an Evanescent Field

The effect of light-pressure forces of an evanescent electromagnetic wave formed by total internal reflection at the interface of a dielectric and a liquid on dielectric spherical nanoparticles located in a liquid medium is considered. The phase portraits of the equations of particle transportation by an evanescent field are investigated taking into account the resistance force of the medium. It is shown that various phase portraits can be realized both without special points and with one special point (stable focus or stable node) on the phase plane, depending on the parameters of the laser radiation and the material of the nanoparticle suspended in water.
