Abstract

The meshless method has strong abilities for conformal modeling and multiphysics coupling. This study pioneers the application of the meshless local Petrov-Galerkin (MLPG) method in the trajectory simulation of charged particles in static axisymmetric electric and magnetic fields, enhancing simulation accuracy and simplifying the treatment of multiphysics coupling issues. The MLPG method is introduced to solve the electric field. Then the field mapping between the electric field and electron trajectories can be easily realized by combining the node sets, which are used to discretize the problem domain and the electron trajectories. In the mapping process, a simple interface processing technique is also proposed. The numerical experiments indicate that the MLPG method has a higher accuracy than the traditional finite difference method (FDM) and finite element method (FEM) under the same element size. The proposed meshless-based method is also verified by analyzing the magnetron injection gun (MIG) of an 800 GHz gyrotron and comparing the results with the particle-in-cell (PIC) simulation.

期刊介绍： IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
