| Abstract | ||
| In this work, double layer and three antireflection coating were designed and simulated , optical reflection values were deduced with a matrix formulation via a personal computer using matlab program, six materials has been selected to investigated of the reflection as function of wavelength in visible region and near IR between (400-1200 nm) on silicon substrate and central wavelength at (900) nm the result show double layer quarter-quarter wave optical thickness has good preference antireflection has been reduced reflection from (32%) for silicon surface to (3%) and for three layer coatings , the results obtained broadband antireflection spectra and several form antireflection that have zero reflection in double and three layer antireflection coating. | ||
