The Effect of Oxidation on the Far-Field Scattering of Aluminium Patch Antennae from Visible to UV
Figure 1
Complex dielectric function for Al + Al2O3 calculated with the effective medium approach. For the complex permittivity, , we show the real, (a), and imaginary, (b), parts for particles with varying volume fractions of Al, where corresponds to pure Al2O3 and to pure Al particles.
