从宏观角度看:全反射情形下,入射波将完全被反射回原介质中,但根据电磁场理论,入射波并非简单地全部返回原介质。该文以电磁理论为出发点,定量计算了折射波在光疏介质中的透射深度、能流密度和反射波的位相变化,进而对全反射现象的物理机制进行了微观分析。最后得出结论:从微观角度看:全反射情形下电磁波并不完全被反射,在第二介质中仍存在折射波。
From a macro point of view: In the case of total reflection, the incident wave will be completely reflected back to the original medium, but according to the electromagnetic field theory, the incident wave does not simply return to the original medium. Based on the electromagnetic theory, this paper quantitatively calculates the transmission depth, energy flux density and the phase change of reflected waves of refracted waves in optical thin-sparse media, and then makes a micro-analysis on the physical mechanism of total reflection. Finally, the conclusion is drawn: From the microscopic point of view: the electromagnetic wave is not reflected completely in the case of total reflection, and there is still refraction wave in the second medium.
