Generation of an Ultra-Long Optical Needle Induced by an Azimuthally Polarized Beam
Publicerad 2021-01-01Hämta fulltextIn this manuscript, a method of generating an ultra-long optical needle (depth-to-width ratio 37.5:1) is proposed and demonstrated by focusing an azimuthally polarized beam. In theory, the action mechanism between the incident beam and the amplitude modulation element, the spiral phase modulation el...

The Emerging Role of Biomass in Complementing a Renewable Energy Portfolio: A Review
Publicerad 2025-07-01Hämta fulltextPlant materials throughout the world, i.e. biomass, can provide annually roughly 18 x 1015 Watt-hours (6.5 x 1013 MJ) of energy, considering just the residues from agriculture and forestry. However, at least part of that amount has higher-valued uses, including being made into durable products, ther...
