               THE FOURTH QUADRANT: A dream comes true

Left Handed Materials (LHM) are artificial composite structures which, as a
result of resonances, exhibit over a frequency range, negative permittivity,
negative permeability and, consequently, negative index of refraction. These
materials exhibit striking and novel electromagnetic behavior such as negative
refraction, flat lenses, absence of reflection, amplification of evanescent
waves, and higher resolution than the diffraction limit.

Recent work is focused on reducing the unavoidable losses, possibly through
new and, hopefully, simpler designs, and on pushing the frequency range of
their operation towards the optical regime.
