Abstract: (1862 Views)
photo-thermal phenomena, which is defined as heat generated in nanostructures by a given spectrum of light, has drawn a large attention to itself, especially in medical researches. In this study, we considered a gold diabolo structure as reference, and then developed new structures in order to improve their electrical and magnetic fields, generated by a plane-wave source, and also to reduce the scattered power in these structures and Al2O3 substrate By these intentions we managed to confine the absorbed power (at the plasmonic wavelength), and to increase the power per unit volume as large as one order of magnitude (10 times as reference). This leads to an increase in the total power absorption from 0.2 normalized in the reference, to 0.45 normalized in the latter structure. We observed an acceptable reduction in scattering power within bipyramid structures and an increase in electric and magnetic fields in other structures as well.
