Multipactor is an electron discharge driven by secondary electron emission (SEE) that plagues microwave components, accelerator structures, and space-borne systems operating in vacuum conditions. Recently, a novel map-based theoretical approach for multipactor based on nonlinear dynamics and chaos theory has been introduced and applied to systems driven by a standard radio frequency (RF) sinusoidal electric field. This theory, however, is universal in that it is applicable to any periodic RF waveform. To demonstrate this, this article applies the map-based theory to periodic rectangular and triangular RF waveforms in a parallel-plate geometry. Bifurcation diagrams are constructed that concisely summarize the underlying multipactor dynamics for both waveforms. These theoretical predictions are then quantitatively verified with the particle-in-cell simulations.

基于映射的多因子理论在交替周期射频波形中的应用
Multipactor 是一种由二次电子发射 (SEE) 驱动的电子放电,它困扰着在真空条件下运行的微波组件、加速器结构和星载系统。最近,已经引入了一种基于非线性动力学和混沌理论的新型基于映射的多分量理论方法,并将其应用于由标准射频 (RF) 正弦电场驱动的系统。然而,该理论是通用的,因为它适用于任何周期性 RF 波形。为了证明这一点,本文将基于映射的理论应用于平行板几何中的周期性矩形和三角形射频波形。构建的分叉图简洁地总结了两种波形的基本多分量动态。
