Russian physics journal Vol. 64, № 8. P. 1560-1565Abstract: The concept of the negative refractive index with application to doubly negative metamaterials is critically analyzed. The positive value of the refractive index is consistent with the definition of the refractive-index vector and the wave vector. A simple method for calculating the complex refractive index for dissipative isotropic materials using the concept of the wave-type identifier is presented.
