电磁波负性运动与媒质负电磁参数研究

Study on the Theory of Negative Characteristic Electromagnetic Wave Motion and the Negative Electromagnetic Parameters

用经典力学分析有质有形物体的运动时,速度是矢量,负速度表示反向运动。但对无质无形的波的运动而言,速度可为标量,不能说负速度仅代表流向反了过来。该怎样理解这种现象的含意?对负波速(NWV)而言,例如当脉冲通过特定媒质时具有负群速(NGV),数值为c/n g(n g<0),它不仅比脉冲通过真空时的速度(光速c)快,而且快到进入媒质前就离开了媒质。由此本文提出了"电磁波负性运动"的概念,并将其与简单的"反向运动"相区别。我们必须接受D'Alembert方程的超前解,理解负速度概念。可以说,自然以她的真实和丰富给我们上了一课,今后她还将继续教导我们。事物的二元性是世界的本质。在现代物理学中,电磁参数成为负值或电磁波作负性运动均常有发生。物理参数为正或为负的本身是自然界对称性机制之一,对其作研究是探索客观规律的一个新途径。

When we use the classical-mechanics analyze the motion of substance, who has inherent mass and shape, the velocity is vector, then the negative velocity express backward direction. But when we dis- cuss the motion of waves, who has not inherent mass and shape, the velocity is scalar, the negative velocity does not obey that rule, i. e. does not indicate only the direction of movement is flow backward. But what does that phenomenon mean？ The negative wave velocity（NWV） means that, for example, a pulse propa- gates in special medium with a negative group velocity（NGV） of c/ng （ng 〈 0）, then it is not only faster than a pulse travelling in vacuum, but so quickly that if left the medium before it had even finished ente- ring. In this paper, we establish the concept of ＂negative characteristic motion of electromagnetic waves＂, and we differentiate it from the meaning of ＂movement in backward direction＂. We must receive the ad- vanced solution of D＇Alembert equation,and understand the concept of negative wave velocity. The truth- ful and rich of Nature give a lesson for us, and she will still instruct us continually in the future. The dualistic nature of matter is basic feature of the world ; and the possibility of electromagnetic pa- rameters in modern physics become negative value or negative characteristic motion of electromagnetic waves can exist everywhere. The positiveness and negativeness of physical parameters are one of symmetry in nature. Then, the study on this investigation area is the new way for research of objective laws.
