Abstract

In this work, the extinction spectra of the nano-structure of the Tilt Helical and Stair-like Towers of Mn thin films were obtained using discrete dipole approximation (DDA) simulation for both s-and p-polarization at two incident light angles of 10° , and 60° at different azimuthal angles for the there samples with different tilt. Obtained results are compared with the experimental optical extinction spectra. The plasmonic peaks appeared at wavelength about 600 nm for both experimental measurments and theory calculations. The experimental spectra for some of the samples are changed in some of the azimuthal angles which are called spectral abnormal. These abnormals is due to the change of the tilt angle and increasing the shadowing effect in the structure of the film, which this may cause increasing the surface fraction of void and forming defects in the structure. However, in the simulation results are not observed these obnormals beacause the voids and defects in the structure becomes negligible and this is the most difference important in spectra obtained for both the experimental and theory results.
