Magnetic Localized Surface Plasmons [PDF]
Physical Review X, 2014 Here, we introduce the concept of magnetic localized surface plasmons (LSPs), magnetic dipole modes that are supported by cylindrical metal structures corrugated by very long, curved grooves. The resonance wavelength is dictated by the length of the grooves, allowing us to tune it to values much larger than the size of the particle.

Femtosecond Autocorrelation of Localized Surface Plasmons
Nanomaterials, 2023 Plasmon electronic dephasing lifetime is one of the most important characteristics of localized surface plasmons, which is crucial both for understanding the related photophysics and for their applications in photonic and optoelectronic devices. This lifetime is generally shorter than 100 fs and measured using the femtosecond pump–probe technique ...

Direct imaging of localized surface plasmon polaritons [PDF]
Optics Letters, 2011 In this Letter, we report on dark field imaging of localized surface plasmon polaritons (SPPs) in plasmonic waveguiding bands formed by plasmonic coupled cavities. We image the light scattered from SPPs in the plasmonic cavities excited by a tunable light source.

Gold nano-ripple structure with potential for bio molecular sensing applications
Sensing and Bio-Sensing Research, 2016 We introduce a simple and cost-effective scheme for bio-sensing using nano-ripple structures. One dimensional metallic nano-ripple structures formed by gas cluster ion beam irradiation have shown polarization of light as well as localized surface plasmon
