主要理論成果

光子的電磁波理論

1987年,趙雙任提出並發表了電磁場的「互能定理」[1][2][3],公式如下:

 

他還提出了兩個電磁場內積的概念:

 

2017年,趙雙任將該定理擴展為「互能流定理」[4],其表達式為:

 

趙雙任提出的電磁場定律指出,電磁輻射不溢出宇宙,


 

並推導了相關公式。他認為電磁波的電場與磁場應保持90度相位差。趙認為經典電磁理論把磁場定義為矢量勢的旋度有局限性,只在准靜態電磁場條件下有效。這個磁場其實是環路上的平均磁場,而不是真正的磁場。趙通過互能流定律重新定義了電磁波的磁場。 [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24]

對經典電磁場理論的磁場的修正

在頻域滯後矢量勢和超前的矢量勢定義為:

 

其中頻域電流定義為  

趙認為經典電磁理論中把矢量勢的旋度定義為磁場是有局限性的。這個定義只對準靜態條件成立。其實矢量勢的旋度不是磁場,而是沿著環路上的平均磁場:

 

磁場上面一橫表示沿著環路的平均磁場,上式第一部分是輻射近場,第二部分是輻射遠場。平均磁場在准靜態條件下和磁場一致。而(真正正確的)磁場可以由平均磁場修正得到:

 

下標   表示近場,  表示遠場。類似的對於超前勢,

 

修正公式為:

 

趙認為,惠勒費曼在吸收體理論 [25] [26] 中提出的電流輻射一半滯後波一半超前波是正確的。

 

 

  是電場,  是滯後的電場,  是超前的電場。

電磁波的磁場的定義和測量

這個(真正正確的)電磁波的磁場的定義可以由互能流密度定義,即

 

其中   是探測偶極子接收天線的磁場。假定電磁波的電場為

 

趙不假定電磁波的磁場和電場同相位,而認為,

 

其中   是一個包含相位的複數。偶極子接收天線   的負載是純電阻的,因此上述互能流密度的兩項都是實數。

  是被測磁場,根據上式,在測量接收天線位置,  的相位和   相同。   同相位。  和接收偶極子天線的電流同相位。所以有:

 

 

 

 

所以

 

這樣可以定出磁場   的相位。所以磁場   式中的相位因子可以定出為  

這和前面修正的滯後磁場的結果一致。至於磁場的大小   和平均磁場的大小   一致。這樣按照趙的理論電磁波是無功功率的。因為電磁波的電場和磁場保持90度相位差。電磁波不是電場和磁場相位相同!電磁波是無功功率的,那麼電磁波平均地看是不傳遞能量的。能量是由互能流傳遞的,而趙認為互能流是粒子。因此粒子包括光子傳遞能量,而波不傳遞能量。這樣波就不必是概率的,也不必坍縮。這對波粒子二象性問題的詮釋提供了一個正確的選擇。


量子力學

自2017年起,趙雙任開始用互能流解釋量子力學,認為任何粒子都是一種互能流。光子是與麥克斯韋方程相關的互能流,電子則是與薛丁格方程或狄拉克方程相關的互能流。他將電磁場理論中的互能流定律推廣應用到量子力學,並將能量流與互能流進行了統一[27]

醫學成像

在CT圖像重建方面,趙雙任提出了基於傅立葉變換的扇形光束和錐形光束CT圖像重建算法。該算法 [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39] 獲得大量引用。 另外在腦磁圖的研究方面趙也做了大量工作 [40] [41] [42] [43] [44]
