Scientific stuff here.
I'm writing an abstract on my own scientific research but my english is not very good :-(.
Is there anyone here who could take a look at this text and explain my mistakes please?
Kind regards.
Some insects such as Papilio blumei or Suneve coronata are known for exhibiting polarization effects like color contrast or geometrical polarization rotation by reflection on their wing scales. The photonic structures found on these species and showing these properties are multilayered spherical cavities or triangular grooves which polarize the light due to inner multiple reflections. Such polarization effects in addition to intrinsic color mixing properties of these photonic structures are interesting in the anti-counterfeiting field thanks to their invisibility to the naked eye. In this paper, we report a micro fabrication technic to produce bio-inspired cylindrical (C-groove) and triangular grooves (V-grooves) that exhibit the same properties. Theoretical analyses were performed by multi-scale simulation (MS) as well as by finite-difference time-domain (FDTD) to compare the polarization capacity of both structures. The V-grooves show the best polarization contrast with a specular spectrum while C-grooves show less polarization effect but have a dispersive spectrum. In both case, the structures show additional optical properties such as diffraction, macroscopic color contrast under polarizer and contrast inversion due to the geometry which contribute to their uniqueness.
