“…PDM improves communication in turbid waters, enhances beam alignment and stability, addresses underwater geographical variations, and offers energy efficiency. In 2022 [28], authors established a high-capacity wireless millimeter-wave (mm-wave) signal delivery system at the W-band using photonics-aided mm-wave generation and polarization division multiplexing (PDM). The authors successfully transmitted PDM-QPSK, PDM-16QAM, and PDM-PS-64QAM mm-wave signals at 10 Gbaud over distances up to 4.6 km.…”

The majority of the Earth’s surface is covered by water, with oceans holding approximately 97% of this water and serving as the lifeblood of our planet. These oceans are essential for various purposes, including transportation, sustenance, and communication. However, establishing effective communication networks between the numerous sub-islands present in many parts of the world poses significant challenges. Underwater optical wireless communication, or UWOC, can indeed be an excellent solution to provide seamless connectivity underwater. UWOC holds immense significance due to its ability to transmit data at high rates, low latency, and enhanced security. In this work, we propose polarization division multiplexing-based UWOC system under the impact of salinity with an on–off keying (OOK) modulation format. The proposed system aims to establish high-speed network connectivity between underwater divers/submarines in oceans at different salinity levels. The numerical simulation results demonstrate the effectiveness of our proposed system with a 2 Gbps data rate up to 10.5 m range in freshwater and up to 1.8 m in oceanic waters with salinity up to 35 ppt. Successful transmission of high-speed data is reported in underwater optical wireless communication, especially where salinity impact is higher.

“…Due to the increasing demands for high data rate, millimeter‐wave (mm‐wave) wireless communication have attracted extremely high attention, for example, the W‐band (75—110 GHz) can support broadband communication up to 10 GHz band and 110 Gbps data rate 1 . Since mm‐wave electromagnetic signal suffers high loss in the air, phased‐array systems consisting of multiple elements are developed to improve the system performance, particularly the long‐distance links 2,3 .…”

In this article, a behavioral model for RF vector‐sum phase shifters is developed to estimate their behavioral and guide the phased‐array front‐end system design. According to their building blocks, the model consists of two typical parts, quadrature signal generator and variable gain amplifiers (VGAs). The modeling process for the quadrature signal generator is based on a complex curve fitting method. For the linear VGA, the polynomial fitting method is used to fit the gain and phase responses of the VGA, the first variable is frequency, and the second variable is the control voltage. Then the complex curve fitting method is used to achieve the final frequency response. Finally, the layout simulation results of an actual phase shifter circuit are used as input, and the two modules are modeled and compared with the measured results to verify the usability of the model.

“…However, an unavoidable difficulty is that TiO 2 ‐based coatings cannot maintain long‐term stability without UV light exposure, along with the degradation of organic components on TiO 2 . [ 32 ] In contrast, the introduction of SiO 2 ‐based coatings can circumvent the problems above, and the lower refractive index of SiO 2 coatings provides higher optical transmittance than TiO 2 coatings only. The modification of SiO 2 ‐based coatings has been intensively explored to support antifogging, their superhydrophilicity was reported to be related to the concentration of hydroxyl groups (SiOH), rough surface, and film porosity.…”

as goggles and visual laryngoscopes has severely hampered the work for medical practitioners. In our daily life, we are tired of fogging on swimming goggles, helmet visors, face shields, commercial freezer windows, automobile LED headlights, etc. The blurred vision caused by fogging brings potential safety hazards to aviation and traffic. [3][4][5][6] Therefore, effective and long-lasting antifogging means are of great importance to those practical applications. Currently, two main categories of antifogging strategies have been developed. The first strategy is closely related to the regulation of environmental parameters. By controlling the relative humidity, temperature, and surrounding air flows to achieve the purpose of surface antifogging. However, the scope of its application has greatly been restricted due to the energy consumption, time consuming, materials selection, and mist elimination equipment design and maintenance. Another antifogging strategy mainly focuses on regulating the surface wettability. [7][8][9][10][11] So far, both superhydrophilic and superhydrophobic surfaces are highly sought after by researchers due to its manageable properties, better cost effectiveness, and potential long-lasting antifogging performance. [12,13] The preparation of superhydrophilic surface is a relatively more effective method to inhibit fog formation. Compared to superhydrophobic surfaces, superhydrophilic surfaces tend to exhibit faster evaporation rates, on which the water droplets uniformly spread out due to the higher affinity to the surface and the quick coalescence of water droplets, promoting the formation of a faster fog-free interface. [14] In addition, the uniform water film on superhydrophilic surfaces can prevent unfavorable light scattering and reflection, particularly the applications in transparent windows such as optical devices, energy-conversion instruments, and outdoor greenhouses. [15] Great interests have been shown in constructing micro-geometric structures on solid surfaces and combine them with chemical modifications to achieve various special wettability. [16] However, the resulting structure usually reduces the mechanical strength, followed by bringing about a serious optical loss, which basically refers to two sides as follows: i) One is the enhanced reflection caused by the surface roughness, when the texture size is greater than the wavelength of incident light, and ii) the other is the refraction on the rough surface (Rayleigh scattering). Those drawbacks will undoubtedly limit the application of thin films on transparent windows. [17] Therefore, it is imperative to take those problems into comprehensive consideration to get In this work, a novel multifunctional film with durable antifogging performance and remarkable optical property is designed. By doping and hybridization to build an organic-inorganic siloxane network, the surface achieves long-lasting wettability and superhydrophilicity with a water contact angle of 0°, which is maintained within 10° for over 130 days. The low refr...
