摘　　要：根据经典力学、电磁学知识和经典色散理论导出了介质对高频电磁波的色散规律,由此色散规律可以清楚看出几乎所有介质对于高频电磁波来说都成为透明介质,并以金属铜为例进行了验证.据此人们可以容易地理解高频电磁波的某些应用.According to the classical dispersion theory, we derive the dispersion law of medium to high frequency electromagnetic wave. From this law we know that almost all the mediums are transparent for high frequency electromagnetic wave. Therefore, the latter can pass through the former. This conclusion is proved with copper for an example. One can understand some application about high frequency electromagnetic wave by means of this conclusion.
