Search for the ideal plasmonic nanoshell: the effects of surface scattering and alternatives to gold and silver

Blaber Martin; Arnold Matthew; Ford Michael (American Chemical Society, 2009)
Sensors based on monochromatic interrogation of a localised surface plasmon resonance

Kealley Catherine; Arnold Matthew; Porkovich Alexander; Cortie Michael (Elsevier Science, 2010)

The localised surface plasmon resonance in gold nanoparticles can be used as the basis of a refractometric sensor. Usually, this is accomplished by monitoring a shift in wavelength of the resonance peak, a task which ...
Structurallyperturbed chiral Bragg reflectors for elliptically polarized light

Hodgkinson Ian; Wu Qi; De Silva Lakshman; Arnold Matthew; Lakhtakia Akhlesh; Mccall Martin (Optical Society of America, 2005)

The structure of an inorganic chiral medium represented as a stack of identical form-birefringent layers that twist steadily with increasing thickness is perturbed by realigning a fraction of each layer to a fixed ...
Subwavelength Optical Imaging Of Evanescent Fields Using Reflections From Plasmonic Slabs

Arnold Matthew; Blaikie Richard (Optical Society of America, 2007)
Supermodes of chiral photonic filters with combined twist and layer defects

Hodgkinson Ian; Wu Qi; De Silva Lakshman; Arnold Matthew; Mccall Martin; Lakhtakia Akhlesh (American Physical Society, 2003)

We consider the circularly polarized localized modes of chiral photonic structures with combined central twist and isotropic layer defects. The general filter is shown to suffer from anomalous remittance and saturation ...
Transmitting Hertzian Optical Nanoantenna with Free-Electron Feed

Denisyuk A; Adamo Giorgio; Macdonald Kevin; Edgar Jonathan; Arnold Matthew; Myroshnychenko Viktor; Ford Michael; Javier Garcia De Abajo F; Zheludev Nikolay (American Chemical Society, 2010)

A pair of coupled gold nanorods excited by a beam of free electrons acts as a transmitting Hertzian antenna in the optical part of the spectrum. Significantly enhanced resonant emission is observed from the antenna when ...
Universal scaling of local plasmons in chains of metal spheres

Arnold Matthew; Blaber Martin; Ford Michael; Harris Nadine (Optical Society of America, 2010)

The position, width, extinction, and electric field of localized plasmon modes in closely-coupled linear chains of small spheres are investigated. A dipole-like model is presented that separates the universal geometric ...
