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)
“There is ... in every child a painstaking teacher, so skilful that he obtains identical results in all children in all parts of the world. The only language men ever speak perfectly is the one they learn in babyhood, when no one can teach them anything!”
—Maria Montessori (1870–1952)
“The awareness of the all-surpassing importance of social groups is now general property in America.”
—Johan Huizinga (1872–1945)
“Each class of society has its own requirements; but it may be said that every class teaches the one immediately below it; and if the highest class be ignorant, uneducated, loving display, luxuriousness, and idle, the same spirit will prevail in humbler life.”
—First published in Girls’ Home Companion (1895)
“As long as the “woman’s work” that some men do is socially devalued, as long as it is defined as woman’s work, as long as it’s tacked onto a “regular” work day, men who share it are likely to develop the same jagged mouth and frazzled hair as the coffee-mug mom. The image of the new man is like the image of the supermom: it obscures the strain.”
—Arlie Hochschild (20th century)
