“…For some authors, digitalization is the integration of digital technologies into business processes [7][8]. For others, it is an organizational strategy deployed using digital resources to create value [9]. A third definition that seems adequate is that digitizing represents a fundamental change in traditional business practices by redefining new capabilities, processes, and relationships [10].…”

Due to the new possibilities offered by digital technologies, more and more companies are embarking on a process of digitizing their supply chains. This dynamic seems to be the opportunity to analyse the impact that digital technologies may have on one of the phenomena that disrupt financial flows within supply chains, and that can alter the companies' treasury, namely that of cash flow bullwhip (CFB). The results of the systematic literature review that was carried out allow to affirm that several technologies can contribute positively to limiting this phenomenon and this by acting on these operational causes, which are the reliability of forecasts, batch orders, the fluctuation in sales prices, rationing games, and lead times.

“…The disadvantages of such polarizers are their narrow band and the complexity of the design of the swing mechanism. Results of the analysis of the characteristics limitation of promising compact polarizers of electromagnetic waves are analyzed in References 25 and 26 The design consists of resonant irises with rectangular slots. The authors carried out a multiparameter optimization of the design in order to determine the limiting characteristics of devices for various frequency ranges.…”

A novel design of the polarizer based on a square waveguide with four posts and four irises for Ku‐band 10.7–12.8 GHz is proposed. The main advantage of the developed polarizer design is the option to tune its polarization characteristics by variation of the posts height. The equivalent circuit of the polarizer has been obtained using scattering and transfer matrices technique. Using this model, the polarization and matching characteristics of the suggested polarizer were optimized simultaneously using the trust region method. This method is reliable and robust since it provides good convergence properties. The novelty of this study lies in the use of a new waveguide polarizer structure based on a combination of irises and posts. Posts enable fine‐tuning of the polarizer performance, while irises promote wide operating frequency band. The following simulated characteristics of the optimal polarizer design were obtained: VSWR for the main modes of horizontal and vertical polarization is less than 1.47, the differential phase shift is within 90° ± 2.6°, the axial is less than 0.46 dB, and the XPD is higher than 32 dB in the operating frequency range. A developed polarizer can be applied in antenna feeds for satellite communication and radar systems.
