BackgroundNurses comprise over half of the global health care workforce, and the nursing care they provide is critical for the global population's health. High patient volumes and increased medical complexity have increased the workload and stress of

In the past three decades, first principles-based fully kinetic Particle-in-Cell Monte Carlo collision (PIC/MCC) simulations have been proven to be an important tool for the understanding of the physics of low pressure capacitive discharges. However,

This article briefly reviews the theory and modeling of single-surface multipactor discharge on a dielectric, focusing on recent studies on two-frequency RF-field-induced multipactor. A novel multiparticle Monte Carlo simulation model with adaptive t

While the particle-in-cell (PIC) method is quite mature, verification and validation of both newly developed methods and individual codes has largely focused on an idiosyncratic choice of a few test cases. Many of these test cases involve either one-

Multipactor, a sustained electron avalanche driven by radiofrequency (RF), has been extensively studied due to its importance in all RF vacuum electronic devices. In particular, much effort has been made in understanding the phenomenon to mitigate it

This article presents the frequency-domain analysis of multipactor discharge on a single dielectric surface. We employ the multiparticle Monte Carlo simulation model in one dimension with adaptive time steps to obtain the temporal profiles of the nor

In this Letter, the novel physics of higher harmonic (HH) generation of the normal electric field near a dielectric surface is reported in multipactor induced plasma ionization breakdown, as determined by kinetic particle-in-cell simulations. The obs

In this work, we characterize the formation and transition behaviors of a microplasma around a microstructured surface at different gas pressures via two-dimensional particle-in-cell/Monte Carlo collision simulations. It is found that the microdischa
