    . Simulations have shown a competitive effect from two structural anisotropy sources, causing a band gap suppression for one of two linear polarizations, and high polarizing ability. Simulations were compared to the measurements with a very good agreement in spectral response. Subwavelength column arrays were

    porous metal. Anisotropic magnetic response was observed in silver columns away from the plasma resonance. Combined with a large permittivity in the infrared, this has potential for future refractive index engineering.

    In this thesis, a new technique named vapour-liquid-solid glancing angle deposition (VLS-GLAD) will be used to enhance structural control over branched nanowire (NW) arrays. NWs are 1D crystals that have been extensively applied in sensors, photovoltaic devices, and transistors. The functional

    also be used to enable the fabrication of azimuthally aligned nanotrees without requiring epitaxy at the substrate. Aperiodic signals will be encoded into diameter oscillations along the length of branches by engineering their local shadowing environment using dynamic substrate motion during growth
