摘要

我们将在这里考虑场射极阵列(FEA)组件的微观尺寸及其有限电导率对尖端末端射频电场(从而发射电流)的影响。在高频场发射结构中存在几种不同寻常的效应，因此我们将分析分解为考虑几个模型系统。

Frequency dependence of field enhancement factor for field emission cathodes with finite conductivity

We will consider here the influence of microscopic dimensions of field emitter array (FEA) components and their finite conductivity on RF electric field on the tip ending (and hence emission current). Several unusual effects exist in field emission structures at high frequencies, so we decompose our analysis into consideration of several model systems.
