Long-term changes in Al thin-film extreme ultraviolet filters

Long-term changes in Al thin-film extreme ultraviolet filters

Skinny-film Al filters are very fashionable owing to their excessive transmittance within the wavelength vary of 17-67 nm and low transmittance within the seen and near-UV areas; nonetheless, they’re susceptible to oxidation. The amorphous Al2O3 layers on the Al surfaces have a lot smaller transmittance than the majority Al materials; due to this fact, they strongly affect…

Research on the lossless contention MAC protocol and the performance of an ultraviolet communication network

Research on the lossless contention MAC protocol and the performance of an ultraviolet communication network

Ultraviolet (UV) communication has been the subject of intensive current analysis resulting from its non-line-of-sight (NLOS) communication, anti-interference, and excessive confidentiality. Given the dearth of the UV Media Entry Management (MAC) protocol, this paper proposes a UV lossless rivalry MAC (UVLLC-MAC) protocol creatively. This MAC protocol is predicated on the superposition logic of UV energy,…
