Results and Importance of First Published Work
His first paper was "The Electrodynamics of Substances with Simultaneously Negative Values of ε and μ". Up to this point, refractive index was traditionally regarded as having only positive values. In this paper he was able to show that refractive index may also be negative. He hypothesized that negative refraction can occur if both the (electric) permittivity and the magnetic permeability of a material are negative. This prediction was confirmed 33 years later when David Smith et al., created a composite material with negative refractive index, and Sir John Pendry showed that the planar lens proposed by Veselago can indeed provide greatly improved resolution.
After Smith's and Pendry's accomplishments with metamaterials, Veselago realized that the most important contribution of his original paper is not that a composite material can be designed to produce a negative refraction, but that a composite material can be designed to produce any value for permittivity and permeability. At least a part of his research goals was then to critically reconsider all formulas of classical electrodynamics that involve permittivity, permeability or refractive index. The fact that prior research is based on positive values for these parameters leads to erroneous solutions when negative values are considered or researched. He stated that many of these formulas need to be corrected.
Veselago perceived that the next big breakthrough with metamaterials will be the fabrication of transparent low-absorption metamaterials with negative refraction in the visible spectrum range.

Famous quotes containing the words published work, results, importance, published and/or work:
“Literature that is not the breath of contemporary society, that dares not transmit the pains and fears of that society, that does not warn in time against threatening moral and social dangers—such literature does not deserve the name of literature; it is only a façade. Such literature loses the confidence of its own people, and its published works are used as wastepaper instead of being read.”
—Alexander Solzhenitsyn (b. 1918)
“Nothing is as difficult as to achieve results in this world if one is filled full of great tolerance and the milk of human kindness. The person who achieves must generally be a one-ideaed individual, concentrated entirely on that one idea, and ruthless in his aspect toward other men and other ideas.”
—Corinne Roosevelt Robinson (1861–1933)
“Kitsch is the daily art of our time, as the vase or the hymn was for earlier generations. For the sensibility it has that arbitrariness and importance which works take on when they are no longer noticeable elements of the environment. In America kitsch is Nature. The Rocky Mountains have resembled fake art for a century.”
—Harold Rosenberg (1906–1978)
“Our fear that Communism might some day take over most of the world blinds us to the fact that anti-communism already has.”
—Anonymous U.S. Analyst In 1967. Quoted in “The Uses of Anticommunism,” vol. 21, published in The Socialist Register (1985)
“If we notice a few errors in the work of a proven master, we may and even will often be correct; if we believe, however, that he is completely and utterly mistaken, we are in danger of missing his entire concept.”
—Franz Grillparzer (1791–1872)
