“…Plasmonic nanostructures are helpful in supporting high frequencies (100 THz) as compared to simple conventional wires (10 GHz). The ability of plasmonic nanostructures to work on high frequency distinguishes them for developing useful electronics such as plasmonstors [189]. In general, lithographic techniques are used in developing electronic devices based on plasmonic circuits [190]- [193].…”

Metal nanostructures have been of great research interest in recent years due to their physicochemical, plasmonic properties and potential applications. A lot of work has been done on the controlled synthesis of metal nanostructures for various applications. In this review, we try to focus on recent developments in synthesis and applications of metal nanostructures. Firstly, we summarized different preparation methods and then briefly explained their potential applications.

“…Surface plasmon resonances in metallic nanoparticles give rise to optical properties that are not available in naturally occurring materials. The ability of surface plasmons to confine light to subwavelength dimensions is useful for several applications including label-free biosensors and optical communication technologies [1]. Simple spherical and linear noble metal antennas can be reshaped to support ring currents and create negative-refractive-index materials [2] while spatial variations of the antenna shape can be used to control the phase of scattered radiation [3].…”

Magnetic circular dichroism of non-local surface lattice resonances in magnetic nanoparticle arrays

Subwavelength metallic particles support plasmon resonances that allow extreme confinement of light down to the nanoscale. Irradiation with left- and right hand circularly polarized light results in the excitation of circular plasmon modes with opposite helicity. The Lorenz force lifts the degeneracy of the two modes in magnetic nanoparticles. Consequently, the confinement and frequency of localized surface plasmon resonances can be tuned by an external magnetic field. In this paper, we experimentally demonstrate this effect for nickel nanoparticles using magnetic circular dichroism (MCD). Besides, we show that non-local surface lattice resonances in periodic arrays of the same nanoparticles significantly enhance the MCD signal. A numerical model based on the modified long wavelength approximation is used to reproduce the main features in the experimental spectra and provide design rules for large MCD effects in sensing applications.
