The transmission matrix method was applied to model the reflection and transmission co-polarization spectra of zig-zag aluminum thin films by different arm numbers and lengths and the optical spectra of the zig-zag nanostructures for both s- and p- polarized lights were obtained at different incident angles. According to the results, for the s- polarized incident light, the transmission reduces and the reflection increases by incident angle. For the p- polarized light, the reflection reduces else for the incident directions near the Bruster’s angle and the transmission almost remains constant. The numbers of Bragg peaks via arm number were also considered for s-polarized light at the 〖60〗^° incident angle. The results determined four arms as the period of zig-zag structure. Besides, the red and blue shifts were observed for the wavelengths smaller and greater than 550 nm, respectively. At last, no Bragg peak was observed for p-polarized light at all incident angles.

Zig-zag Al nanostructures were fabricated on the glass and steel using thermal evaporation technique. The structural, morphology and electrical properties of Al thin films were studied by using AFM, FESEM and four-point probe instrument. FESEM analysis showed that the grains are distributed on the zig-zag Al-glass and their shape is polygonal while the grains on the zig-zag Al-steel surface have a non-uniform distribution and the shape of the grains is oval. AFM analysis indicated the surface roughness of zig-zag Al-steel nanostructures is more than the zig-zag Al-glass. Moreover, the wrinkles on the zig-zag Al-steel and the small protuberances on the zig-zag Al-glass observed. The anisotropy of electrical was performed in two perpendicular directions x and y of the samples surface. The average electrical resistivity of the zig-zag Al films on glass and steel produced were obtained about 4.69×10-8 and 5.85×10-8 Ω.m, respectively. Simulation results by the perturbation method agree with the experimental results. Manuscript profile
