چکیده:

In this paper the reflection coefficient of a mixture of glass oxide and nanograins of some noble metals (gold, silver and copper) have been derived using Tmatrix approach. In addition the effect of spherical metallic nanograin shape on the resonance shift of the reflection coefficient has been analyzed and the associating plots have been plotted. For the three investigated metals, their resonance wavelengths have been altered according to the shapes and orientation of the grains relating to each other. The results obtained from the two used methods, confirm the authenticity of each other
