                 The quest for optical metamaterials

                        E. N. Economou
             Institute of Electronic Structure and Lasers
                      FORTH, Crete, Greece

A brief summary of the basic features of  the so called Left-Handed 
Metamaterials will presented together with the derivation of their 
fundamental electromagnetic properties.For the operational frequency 
range to reach the optical regime the size of the artificial unit 
must be in the nanoregime, i.e., below 100 nm. There the ohmic losses 
become very significant and the kinetic energy of the current carrying 
electrons surpasses the magnetic energy; both  these effects present 
severe obstacles to our path for fabricating artificial  materials with 
amazing optical properties. Several attempts to overcome these obstacles
will be discussed.
