Plasma current behavior is affected by interactions between a cold plasma and a metal object. The plasma charge depends on the surface area of the metal object, which does not provide information regarding the shape of the object. A metal disk has a side edge and a square metal plate has corners. The edge effects associated with the metal disk and plate reflect the relationship between the plasma current and the dynamic electric field due to temporal variation of the applied voltage. When the object has a small surface area, the plasma current is inversely proportional to the dynamic electric field because the side edge is affected. The linear correlation between the plasma current and the dynamic electric field is disrupted by the edge effect. When a metal plate surface area is small, the plasma current does not depend on the dynamic electric field due to the effect of corners.

冷等离子体与金属物体相互作用时侧边对等离子体电流的影响

等离子体电流行为受冷等离子体和金属物体之间相互作用的影响。等离子体电荷取决于金属物体的表面积，它不提供有关物体形状的信息。金属盘有侧边，方形金属板有角。由于施加电压的时间变化，与金属盘和板相关的边缘效应反映了等离子体电流和动态电场之间的关系。当物体表面积较小时，等离子电流与动态电场成反比，因为侧边受到影响。边缘效应破坏了等离子体电流和动态电场之间的线性相关性。当金属板表面积小时，
