Short-wavelength stimulated Raman scattering in a silica fiber pumped by an XeBr excimer laser

Symbolic Meta-Modeling of RIS-Assisted FSO Communication Channels

“…). Note that (10), (11), and ( 12) are examples of symbol Meijer G-based models of single LoS FSO links without the RIS infrastructure. Rayleigh, Nakagami-m, Weibull, log-normal, and Gaussian distrinutions can also be derived from the generalized Gamma PDF in (9), by setting (m i , ξ i ) = (1, 1), (ξ i = 1), (m i = 1), (m i , ξ i ) =⇒ (∞, 0), and (m i =⇒ ∞, ξ i = 1), respectively.…”

“…Attenuation determines the transmitted signal strength, which decreases exponentially as the distance between the transmitter and receiver increases. It considers the coefficient of attenuation, which includes both scattering and photon absorption [11]. The pointing error is the angle between the transmitting optical axes with and without wavefront aberrations [12].…”
