AWhat changed
Analyzed electromagnetic propagation when electric permittivity and magnetic permeability are simultaneously negative, deriving reversed relations among wave, energy-flow and refraction directions.
Scientific scope
The record targets the 1967 Russian paper and its 1968 English translation as one work. Later metamaterial designs, experimental negative refraction, perfect-lens proposals and device applications remain separate.
