摘要

本文提出了克服数值切伦科夫不稳定性的线性分析方法。基本上，它是基于求解电磁粒子模拟的显式时间格式。该方案依赖于一个参数，该参数允许我们减少并在某些情况下抑制在这种情况下可能出现的数值切伦科夫不稳定性，并在文献中广泛描述。研究了该方案的一些性质。最后给出了数值例子来说明我们的目的。

A linear analysis to overcome the numerical Cherenkov instability

This paper proposed a linear analysis to overcome the numerical Cherenkov instability. Basically, it is based on a explicit time scheme for solving electromagnetic particle simulations. This scheme depends on a parameter, that allows us to reduce and in some cases to suppress the numerical Cherenkov instability that can appear in this context, and is widely described in the literature. Some properties of the scheme are also investigated. Numerical examples are finally given to illustrate our purpose.
