论文摘要

当准杂色场传播和通过反拨挡涂层,无源,透明,连续的,线性磁电磁介质传播并通过局部框架中的静止状态时,能量弹药张量的形式仍然存在争议。 Minkowski Energy-Momentum Tensor是电磁保护定律的主要组成部分。一个多世纪以来,人们一直知道电磁保护定律并未证明,替代能量弹药张量已提出改善已知的身体缺陷(违反了角度和线性动量的保护),并且通过各种材料能量量量和偶联的力量以及已介绍了已介绍或完善律师的各种材料能量电量和耦合力。现存的分辨率是将连续电磁系统视为子系统,并添加现象学材料子系统能量摩托张量。我们表明,电磁和材料的四个不同,能量量张量会产生一个能量连续性定理,其中两个非零项依赖于折射率$ n $的不同功率。然后,亚伯拉罕·米科夫斯基(Abraham-Minkowski)争议的现有解决是自信的。

The form of the energy-momentum tensor when a quasimonochromatic field propagates into and through an antireflection-coated, sourceless, transparent, continuous, linear magneto-dielectric medium, initially at rest in the local frame, remains controversial. The Minkowski energy-momentum tensor is the main component of the electromagnetic conservation law. It has been known for over a century that the electromagnetic conservation law is unsound as evidenced by alternative energy-momentum tensors that have been proposed to ameliorate known physical deficiencies (violation of conservation of angular and linear momentum) and by the various material energy-momentum tensors and coupling forces that have been introduced to repair or complete the law. The extant resolution is to treat the continuum electromagnetic system as a subsystem and add a phenomenological material subsystem energy-momentum tensor. We show that the four-divergence of the total, electromagnetic plus material, energy-momentum tensor produces an energy continuity theorem in which the two non-zero terms depend on different powers of the refractive index $n$. Then the extant resolution of the Abraham-Minkowski controversy is self-inconsistent.
