摘　　要：不同频率的电磁波在金属材料中,有着不同的导电极限频率。各种金属材料都有各自的高频极限,高频极限是区分材料作为导电体与电介质的分界线。通过建立理想化的金属晶格模型,导出了金属材料的高频极限关系式,从而明确了电介质材料与金属材料的高频频率分界,对于研究电磁波与金属材料的作用机理有着实际意义。Metals material of Various kinds has their own different limit high frequency of electromagnetic wave. The extreme limit frequency is a boundary that distinguishes the materials conductive or actions as dielectric as all metals have different limit in experiment. With the build up of metals lattice model of idealization, it leads the extreme limit frequency relation of the metals material, thus makes the boundary clear about dielectric and conductive metals material, and it＇s important to know the interaction mechanism of electro- magnetic wave and metals material.

关 键 词：电磁波 金属高频极限 介电常数
