INTRODUCTION and Ludvig Lorentz (1829-91) contributed to this problem. When the above method occurs in all direction uniformly, This paper concern with the altered types of surface MIE Scattering is said to happen. MIE theory means the maxima and minima in the design plasmonic nanoparticles mounted in the various substrates to of strength with angle. When the dimension of the particle enhance solar cell efficiency. Using MIE scattering software is higher than or equal to the wavelength of laser, the we can find out the altered types of light scattering and scattering is a complex function with maxima and minima absorption shown by multiple types of nanoparticles like gold with respect to angle.

SCRUTINY OF GOLD SAMPLE Fig. 2 CSCA/CABS V wavelength A. Scrutiny of Gold on Glass Medium We have to vary the nanoparticle dimension from QSCA/QABS V wavelength 20nm-200nm and compare the variation in peak wavelengths (CSCA/CABS V Wavelength) / (QSCA/QABS V wavelength).
