Preparing materials with a desired refraction coefficient
A. G. Ramm
A recipe is given for creating material with a desired refraction coefficient by embedding many small particles in a given material. To implement practically this recipe, some tech…
Does negative refraction make a perfect lens?
A. G. Ramm
A discussion of a question, studied earlier by V.Veselago in 1967 and by J. Pendry in 2000, is given. The question is: can a slab of the material with negative refraction make a pe…
Electromagnetic wave scattering by many conducting small particles
A. G. Ramm
A rigorous theory of electromagnetic (EM) wave scattering by small perfectly conducting particles is developed. The limiting case when the number of particles tends to infinity is…
Electromagnetic wave scattering by small bodies
A. G. Ramm
A reduction of the Maxwell's system to a Fredholm second-kind integral equation with weakly singular kernel is given for electromagnetic (EM) wave scattering by one and many small…
