Title

EFFECTIVE REFRACTIVE INDEX OF METAMATERIAL FABRICATED FROM NANOSILVERS

Pages

  -

Abstract

 INTRODUCTION: MUCH EXPERIMENTAL AND THEORETICAL EFFORTS HAS BEEN RECENTLY DEVOTED TO THE STUDY OF A NEW TYPE OF METAMATERIALS THAT HAVE SIMULTANEOUSLY NEGATIVE ELECTRIC PERMITTIVITY Ε AND MAGNETIC PERMEABILITY ΜAND ARE THUS TERMED AS NEGATIVE REFRACTIVE-INDEX MATERIALS (NIM), OR LEFT-HANDED MATERIALS [1]. OVER THIRTY YEARS AGO, VESELAGO [2] PREDICTED THEORETICALLY THAT ELECTROMAGNETIC WAVES PROPAGATING IN ISOTROPIC NIM’S POSSESS SEVERAL PECULIAR CHARACTERISTICS, INCLUDING ANOMALOUS REFRACTION, REVERSAL OF BOTH THE DOPPLER SHIFT AND THE CERENKOV RADIATION, AND REVERSAL OF RADIATION PRESSURE TO RADIATION TENSION [3]. ON THE OTHER HAND, SCATTERING AND ABSORPTION OF LIGHT BY NANOSTRUCTURES IS ONE OF THE PHYSICISTS & CHEMISTS MOTIVATIONS.MIE COULD PROPOSE EXACT SOLUTION FOR LIGHT SCATTERING OF SPHERICAL NANOPARTICLES BY SOLVING OF MAXWELL'S EQUATIONS IN 1908 [3].MIE'S THEORY WAS REPRESENTED FOR ISOTROPIC, HOMOGENEOUS AND SPHERICAL PARTICLES INTOISOTROPIC, HOMOGENEOUS AND NON-ABSORBING SURROUNDING MEDIUMS [4].IN THIS WORK, WE SUGGEST THAT FOR SPECIAL WAVELENGTH AND NANOHOLES SIZE, THE EFFECTIVE REFRACTIVE INDEX SHOWS NEGATIVE VALUE IN MIE'S THEORY AND HENCE IT COULD BE CONSIDERED AS META-MATERIALS.
