title: Polarisation and wavelength selective transmission through nanohole structures with multiple grating geometry

authors: Nemanya, Sedoglavich

subjects: apertures

abstract: Excitation and localization of surface plasmon polariton modes in metal-dielectric structures can be utilized to construct nanophotonic materials and devices with tuneable optical dispersion. We present a selective polariton generator (SPG) device that demonstrates switching of light transmission based on surface plasmon antennae principles. This polarization-sensitive structure selectively generates and transports polaritons of a desired wavelength through subwavelength apertures. Two of these SPGs have been combined around a nanohole into a new, single device that allows polarization and wavelength selective switching of transmission. The multi-state operation is confirmed by experiment results.

title: Enabling collaborative review with the DSpace configurable workflow

authors: Schweer, Andrea

subjects: DSpace

abstract: The DSpace configurable workflow feature enables the creation of custom review workflows beyond the traditional edit metadata, accept, reject actions. This poster reports on our experiences in using the customisable workflow to enable collaborative review by repository management staff for the AgResearch institutional research repository, AgScite.

title: Kaitiakitanga: protecting New Zealand's native biodiversity

authors: Morad, Munir

subjects: geography

abstract: Species diversity is a very important component of a healthy ecosystem, and a necessary condition for long-term sustainable development. However, it is widely recognised that species extinction is on the increase in New Zealand, as biological diversity comes under pressure from landuse activity and environmental change.
