慢衰減波的頻域解釋

Explanation of Slowly Decreasing Wave in Frequency Domain

  • 摘要: 采用頻域傳遞函數(shù)的方法分析了圓盤輻射器的輻射特性，給出了軸線處的近遠場電場、磁場和能量傳播規(guī)律。采用定義了一個能量輻射因子的方法詳細分析了時域電磁波的慢衰減原因。通過分析發(fā)現(xiàn)，其本質(zhì)并沒有任何異于時諧電磁波的地方，只是因為時域電磁波往往具有較寬的頻帶特性，其中高頻成分的輻射能力要比低頻強，從而表現(xiàn)出了所謂的慢衰減特性。通過分析頻域的結(jié)果，使得時頻域分析都能夠獲得一致的認識。
    Abstract: The character of radiation of disk radiator is analyzed with transfer function in frequency domain. Near or far field and law of energy propagation are presented at axes of disk. Time domain electromagnetic waves are analyzed in detail by defining a energy radiation parameter. The nature is the same as sinusoidal electromagnetic wave. They can decrease much more slowly because the radiating capacity of high frequency is better than the low, then coincident understand can be reached between them.
