The article describes a new approach to obtaining the energy-momentum tensorof electromagnetic field in medium without the use of Maxwell's equations andPoynting theorem. The energy-momentum tensor has new qualities andconsequences. Its linear invariant is Lagrange density of the electromagneticfield. From the tensor follows the equation of conservation of energy density,the equation of flux energy density and wave equations for these energy values.Wave equation for momentum density describes simultaneous transfer of momentumand angular momentum regardless of radiation polarization. From the tensorfollow the balance equations of the electromagnetic forces for the momentumdensity in the forms of the Minkowski and Abraham, which proves their equalityand mutual supplementation. Equation for Abraham force is obtained as well. Itis shown that its divergence is equal to zero. Tensor and the balance equationsof electromagnetic forces in a continuous medium are derived.

A new form of the energy-momentum tensor of the interaction of an  electromagnetic field with a non-conducting medium. The wave equations. The  electromagnetic forces
