Reflectance spectrometry techniques with the integration of remote sensing data help us in identifying and mapping the phenomena on the earth. Using these techniques to discriminate the petrologic units independently and without knowing the spectral behavior of rocks along the electromagnetic wavelengths can not be so much useful. For the purposes of this study, 65 samples of igneous and metamorphic rocks from Hamedan region were collected and their spectra were measured using Fieldspec3 device in laboratory. The spectra were analyzed on the basis of absorption, position and shape. Petrographic analyses were used to interpret the absorption patterns as well. Then the spectra were classified according to spectral patterns. This measurement was done on both freshly cut and exposed surfaces of the samples and except a few samples, the two sets of spectra did not differ significantly. Finally, to evaluate the possibility of recognition of these targets, the responses of two hyperspectral and multispectral sensors were simulated from spectra representative of the spectral classes, showing that significant identification and classification of well exposed rocks are potentially possible using remote instruments providing high quality spectra. Also Aster simulation showed that a preliminary gross discrimination of rocks was however possible.

Conductive transparent ZnS/M/ZnS, (M = Au, Ag, Cu, Al) nano-structures have been simulated by optimization layers thickness, and gold, silver, copper, and aluminum materials were used as a metal layer and zinc sulfide for dielectric layers. Then the optimum simulated structure has been fabricated on a glass substrate by thermal evaporation. The crystallinity properties of the structures, such as grain size and lattice parameters, have been calculated from XRD pattern. The optical transmittance and absorption spectra show that the structures are absorber of the ultraviolet and infrared and transparent against visible lights.  These results were confirmed by calculated figure of merit and luminous transmittance and measuring the rate of heat dissipation.
