“…Erbium-doped fibers (EDFs) find widespread applications in the aerospace industry as laser sources and optical amplifiers [104]. In the space environment, where such equipment is frequently exposed to high-energy radiation, ensuring radiation resistance becomes a critical consideration during their design phase [105,106]. Studies have revealed that compared to traditional pure silica-core fibers and germanosilicate fibers, EDFs exhibit superior resistance to radiation [107].…”

In recent years, optical fibers have found extensive use in special environments, including high-energy radiation scenarios like nuclear explosion diagnostics and reactor monitoring. However, radiation exposure, such as X-rays, gamma rays, and neutrons, can compromise fiber safety and reliability. Consequently, researchers worldwide are focusing on radiation-resistant fiber optic technology. This paper examines optical fiber radiation damage mechanisms, encompassing ionization damage, displacement damage, and defect centers. It also surveys the current research on radiation-resistant fiber optic design, including doping and manufacturing process improvements. Ultimately, it summarizes the effectiveness of various approaches and forecasts the future of radiation-resistant optical fibers.

“…Because the optical path is identical in both the clockwise and counterclockwise directions, it is insensitive to environmental effects. The respective intensity of transmission T, reflection R, and loss of the fiber loop A are given by [8]:…”

“…However, the cost of implementing an FBG sensing system frequently limits its applications. A force sensor in which the sensing element is a vibrating metallic glass strip under tension has been reported [8]. The force applied at one end of the specially designed frame is converted into having a proportional change in tension along the strip.…”

tively, and can satisfy the typical bandwidth requirement for dualband WLAN applications.The measured radiation patterns for the proposed antenna at 2.45 and 5.25 GHz are shown in Figures 3 and 4, respectively. It can be seen that the radiation patterns at both frequencies have monopolelike radiation patterns. However, in the azimuthal plane ( x-y plane), the radiation patterns at 2.45 and 5.25 GHz are more similar to omnidirectional radiation. The measurements at the other operating frequencies have similar radiation patterns, as shown in Figures 3 and 4. Figures 5(a) and 5(b) show the antennagain responses measured in the 2.4-and 5.2-GHz bands, respectively. For the 2.4-GHz band, the peak antenna gain is about 1.98 dBi and the gain variation is less than 0.3 dBi. As for the 5.2-GHz band, the peak antenna gain is about 3.95 dBi and the gain variation is within 0.4 dBi. The antenna-gain variations in both bands are actually quite small.
