主要理论成果

光子的电磁波理论

1987年,赵双任提出并发表了电磁场的“互能定理”[1][2][3],公式如下:

他还提出了两个电磁场内积的概念:

2017年,赵双任将该定理扩展为“互能流定理”[4],其表达式为:

赵双任提出的电磁场定律指出,电磁辐射不溢出宇宙,


并推导了相关公式。他认为电磁波的电场与磁场应保持90度相位差。赵认为经典电磁理论把磁场定义为矢量势的旋度有局限性,只在准静态电磁场条件下有效。这个磁场其实是环路上的平均磁场,而不是真正的磁场。赵通过互能流定律重新定义了电磁波的磁场。 [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24]

对经典电磁场理论的磁场的修正

在频域滞后矢量势和超前的矢量势定义为:

其中频域电流定义为

赵认为经典电磁理论中把矢量势的旋度定义为磁场是有局限性的。这个定义只对准静态条件成立。其实矢量势的旋度不是磁场,而是沿着环路上的平均磁场:

磁场上面一横表示沿着环路的平均磁场,上式第一部分是辐射近场,第二部分是辐射远场。平均磁场在准静态条件下和磁场一致。而(真正正确的)磁场可以由平均磁场修正得到:

下标 表示近场, 表示远场。类似的对于超前势,

修正公式为:

赵认为,惠勒费曼在吸收体理论 [25] [26] 中提出的电流辐射一半滞后波一半超前波是正确的。

是电场, 是滞后的电场, 是超前的电场。

电磁波的磁场的定义和测量

这个(真正正确的)电磁波的磁场的定义可以由互能流密度定义,即

其中 是探测偶极子接收天线的磁场。假定电磁波的电场为

赵不假定电磁波的磁场和电场同相位,而认为,

其中 是一个包含相位的复数。偶极子接收天线 的负载是纯电阻的,因此上述互能流密度的两项都是实数。

是被测磁场,根据上式,在测量接收天线位置, 的相位和 相同。 同相位。 和接收偶极子天线的电流同相位。所以有:

所以

这样可以定出磁场 的相位。所以磁场 式中的相位因子可以定出为

这和前面修正的滞后磁场的结果一致。至于磁场的大小 和平均磁场的大小 一致。这样按照赵的理论电磁波是无功功率的。因为电磁波的电场和磁场保持90度相位差。电磁波不是电场和磁场相位相同!电磁波是无功功率的,那么电磁波平均地看是不传递能量的。能量是由互能流传递的,而赵认为互能流是粒子。因此粒子包括光子传递能量,而波不传递能量。这样波就不必是概率的,也不必坍缩。这对波粒子二象性问题的诠释提供了一个正确的选择。


量子力学

自2017年起,赵双任开始用互能流解释量子力学,认为任何粒子都是一种互能流。光子是与麦克斯韦方程相关的互能流,电子则是与薛定谔方程或狄拉克方程相关的互能流。他将电磁场理论中的互能流定律推广应用到量子力学,并将能量流与互能流进行了统一[27]

医学成像

在CT图像重建方面,赵双任提出了基于傅里叶变换的扇形光束和锥形光束CT图像重建算法。该算法 [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39] 获得大量引用。 另外在脑磁图的研究方面赵也做了大量工作 [40] [41] [42] [43] [44]
