Left handed materials - structures with negative
index of refraction
Abstract:
Left handed materials are man-made structures which possess,
in a given frequency interval, negative effective permittivity
and permeability. Experiments of D.R. Smith confirmed
that such materials possess also negative index of refraction.
I give a short review of electro-magnetic properties of
left-handed materials, describe methods of numerical analysis
of transmission of electromagnetic waves through such materials
and discuss their possible applications (perfect lens).
