Local electric field enhancement during nanofocusing of plasmons by a tapered gap [PDF]

, 2007
We demonstrate that during plasmon nanofocusing in a tapered gap (V groove), local electric field experiences much stronger enhancement than the magnetic field.

Mapping of plasmonic resonances in nanotriangles

Beilstein Journal of Nanotechnology, 2013
Plasmonic resonances in metallic nano-triangles have been investigated by irradiating these structures with short laser pulses and imaging the resulting ablation and melting patterns.

Enhanced visual fields in hammerhead sharks [PDF]

Journal of Experimental Biology, 2009
SUMMARYSeveral factors that influence the evolution of the unusual head morphology of hammerhead sharks (family Sphyrnidae) are proposed but few are empirically tested. In this study we tested the ‘enhanced binocular field’ hypothesis (that proposes enhanced frontal binocularity) by comparison of the visual fields of three hammerhead species: the ...

Simultaneous field enhancement and loss inhibition based on surface plasmon polariton mode hybridization

Nanophotonics, 2020
In common plasmonic configurations, energy loss and field enhancement are mutually restricted. In a vast majority of cases, high confinement goes together with high loss, which is a serious limitation for some applications. In an attempt of breaking this

Influence of sinusoidal and square voltages on partial discharge inception in geometries with point-like termination

High Voltage, 2018
High-voltage equipment involves both electrical and electronic components. In electrical power network, which consists of rotating machine, power transformers and transmission lines, field enhancement at critical regions can lead to local breakdown ...

High-Resolution 3D Reconstruction of Individual Rice Tillers for Genetic Studies

Agronomy
The architecture of rice tillers plays a pivotal role in yield potential, yet conventional phenotyping methods have struggled to capture these intricate three-dimensional (3D) structures with high fidelity. In this study, a 3D model reconstruction method

Field Emission from the Perspective Cathodes on the Nanostructured SiC base: a New Approach for the Field Enhancement Coefficient Consideration

Фізика і хімія твердого тіла, 2022
A new comprehensive theory for the field emission from the nanostructured semiconducting SiC was built with allowance for specially worked out analytical model of the field enhancement coefficient for the case of comparatively “smooth” protrusions ...
