Excitation Energy Transfer and Trapping in Higher Plant Photosystem II Complexes with Different Antenna Sizes [PDF]

open access: yes, 2011
700 cm(-1)) and a slow relaxation of the radical pair to an irreversible state (similar to 150 ps). Somewhat unexpectedly, we had to reduce the energy-transfer and charge-separation rates in complexes with decreasing size to obtain optimal fits.

Light-trapping modes in lossy plasmonic waveguides

open access: yesAIP Advances, 2019
Light-trapping modes can exist in lossless plasmonic waveguides. Here, we investigate the effect of metallic loss on light-trapping modes using the usual complex wave vector (β)-real frequency (ω) formulation and an alternative real β-complex ω ...

Design and optical characterisation of an efficient light trapping structure for dye-sensitized solar cell integrated windows [PDF]

open access: yes, 2019
Windows integrated with semi-transparent photovoltaics (PVs) such as Dye-Sensitized Solar Cells (DSSCs) show good potential in improving building performance, in term of providing daylight, reducing unnecessary solar heat gain and also generating ...

Short Report: Influence of Centers for Disease Control Light Trap Position, Relative to a Human-Baited Bed Net, on Catches of Anopheles Gambiae and Culex Quinquefasciatus in Tanzania. [PDF]

open access: yes, 1998
The best position for Centers for Disease Control (Atlanta, GA) light traps, in relation to human-occupied bed nets for trapping of host-seeking Anopheles gambiae Giles and Culex quinquefasciatus Say mosquitoes, was determined in Tanzania.

Trapping light in plasmonic waveguides

open access: yesOptics Express, 2010
We present comprehensive case studies on trapping of light in plasmonic waveguides, including the metal-insulator-metal (MIM) and insulator-metal-insulator (IMI) waveguides. Due to the geometrical symmetry, the guided modes are classified into the anti-symmetric and symmetric modes.
