Recent progress in submicron-and nano-fabrication technologies has led to the emergence
of novel photonic structures such as optical nanoantennas and metasurfaces. Real-life …

A model of cathode spots in high-current vacuum arcs is developed with account of all the
potentially relevant mechanisms: the bombardment of the cathode surface by ions coming …

2-D axially symmetric hydrodynamic model has been developed to describe the formation of
a crater and liquid-metal jets on a vacuum arc cathode using Navier-Stokes equations for an …

Abstract A two-dimensional (2D) rotary axisymmetric model has been developed to describe
the formation and development of cathode spot in vacuum arc. The model includes …

Significance The number of injections administered has increased dramatically worldwide
due to vaccination campaigns following the COVID-19 pandemic, creating a problem of …

A 3D transient model of a cathode-spot crater and droplet formation in a vacuum arc is
developed. The model includes mass, momentum, heat transfer (energy), current continuity …

Arc splitting is one of the most important processes in accomplishing a power interruption by
multiplying the number of voltage drops. During arc-plate interaction, the arc roots erode and …

The formation of microjets is studied during the extrusion of a melted metal by the plasma
pressure from craters formed on a cathode in a burning vacuum arc. An analytic model of …

A model has been developed for the explosive electron emission cell pulse of a vacuum
discharge cathode spot that describes the ignition and extinction of the explosive pulse. The …

Plasma–solid interaction represents a major concern in many applications such as power-
interruption and plasma–metal processing. Characterized by high-current density and …
