The collective electromagnetic response of metal/dielectric particles arranged in fractal aperiodic arrays with sub-wavelength inter-particle spacing has the potential to provide a novel angular and frequency dependence in sensing applications. In this work we would like to analyse the light scattering and orbital angular momentum spectra of various fractal patterned aperiodic arrays of nanoparticles. This study is expected to open novel opportunities for the manipulation of optical properties of fractal based deterministic aperiodic nanostructures for a range of emerging engineering applications in singular optics, secure communication, optical cryptography, and optical sensing.
