金屬軟管組件.波紋形軟管組件的構造和使用指南This means that the dielectric property changes with height and allows a slight increase in the speed of a radio wave as we move upwards through the atmosphere. this in turn means that if a radio wave moves away from the earth at an angle less than 90 degrees, then the upper part of the wave travels faster than the lower part. therefore even under normal conditions this can in effect bend, or refract, the wave back down to earth
其中一種顯著的現象是：在一定的氣象條件下，在大氣邊界層尤其是在近地層中傳播的電磁波，受大氣折射的影響，其傳播軌跡彎向地面，當曲率超過地球表面曲率時，電磁波會部分地被陷獲在一定厚度的大氣薄層內，就好像電磁波在金屬波導管中傳播一樣，稱為大氣波導傳播，形成波導傳播的大氣薄層稱為大氣波導層。分享友人
