论文摘要
根据分散介质中麦克斯韦方程的非本地拉格朗日，该田间的能量弹药张量。我们通过变异方法获得了场方程，并获得了非本地拉格朗日定理的扩展。然后，在一般环境中获得的电磁能量张量是在快速振荡载体上缓慢变化的场的情况。
On the basis of a non-local Lagrangian for Maxwell equations in a dispersive medium, the energy-momentum tensor of the field is derived. We obtain the Field equations through variational methods and an extension of Noether theorem for a non-local Lagrangian is obtained as well. The electromagnetic energy-momentum tensor obtained in the general context is then specialized to the case of a field with slowly varying amplitude on a rapidly oscillating carrier.
