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)
“If family communication is good, parents can pick up the signs of stress in children and talk about it before it results in some crisis. If family communication is bad, not only will parents be insensitive to potential crises, but the poor communication will contribute to problems in the family.”
—Donald C. Medeiros (20th century)
“The chimney is to some extent an independent structure, standing on the ground, and rising through the house to the heavens; even after the house is burned it still stands sometimes, and its importance and independence are apparent.”
—Henry David Thoreau (1817–1862)
“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)
“[My early stories] are the work of a living writer whom I know in a sense, but can never meet.”
—Elizabeth Bowen (1899–1973)
