We present a study of the nonlinear dynamics of charged microparticles in a linear electrodynamic trap at normal pressure and temperature. In this work, will be considered a mathematical modeling of the nonlinear dynamics of a microparticle under viscous friction conditions, as well as experimental confirmation of theoretical results. Based on theoretical and experimental findings, we propose an innovative method for determining charge, mass and size of a certain microparticle localized in the linear electrodynamic trap.

In the present study, we propose a new transparent thin-film ITO surface radio-frequency (RF) trap. Charged hybrid microstructures were localized in the developed ITO trap. We show, analytically and experimentally, that the position of the localization zones in the trapped hybrid structure are stable. The transfer of charged particles between localization zones was studied under the action of gravity-compensating laser radiation. We highlight the advantages of transparent thin-film ITO traps to investigate and manipulate charged particles.

We consider a simple model of charged microparticles trapped in an electrodynamic field and interacting according to Coulomb forces. We reveal a bifurcation of the stable equilibrium point depending on the system parameters. Mathematical modelling of charged particles localization in a linear electrodynamic trap was implemented and effective potential splitting was demonstrated. The obtained splitting of Coulomb crystal corresponds to the experimental results.
