SADEA-optimized metasurface antenna for broadband circular polarization in sub-6 GHz 5G systems
Abstract In this work, a high-gain broadband circularly polarized (CP) metasurface-based printed monopole antenna is proposed for sub-6 GHz 5G covering ambient RF energy harvesting applications & next-generation wireless connectivity links. It starts from a λo/4 linearly polarized (LP) printed monopole and attains its CP by connecting parasitic conducting strip (PCS-L) to partial ground plane with a metallic shorting strip.
Multi-objective hybrid GA-PSO optimized PI control for grid-connected PV-fed cascaded H-bridge multilevel inverter
Abstract The growing integration of PV energy systems into modern power grids necessitates advanced control techniques to maintain stable operation, fast dynamic response, and high-power quality under nonlinear and time-varying conditions. Cascaded H-bridge multilevel inverters (CHB-MLI) are widely adopted for grid-connected PV applications. This study develops a closed-loop control for a PV Integrated on-grid five-level CHB-MLI aimed at enhanced dynamic response and improved power quality.
Implementation of smart metasurfaces for the Sub-6 GHz 5G wireless systems: design, optimization, and its synthesis for enhancing antenna’s performance | Scientific Reports
Abstract A broadened polarization bandwidth with a high-gain SADEA-driven metasurface antenna at 5 GHz is investigated for the sub-6 GHz 5G wireless applications. At first, a λo/4 linearly polarized printed monopole antenna is considered. In the next step, a metallic strip that serves as a dynamic switching mechanism is used to short one of the parasitic conducting strips with a partial ground plane to get circular polarization (CP).

Enhancing the Performance of the INC Algorithm using Kalman Filter for Thermoelectric Energy Harvesting System (THES)
Khalid Yahya, Nassim A. Iqteit, Ibrahim Alhamrouni, Mohamed Salem, Mehmet Zeki BİLGİN Abstract improving the energy harvesting system is requiring an efficient MPPT algorithm which has the ability to track the optimum power under steady state and dynamic state. in this paper, incremental conductance MPPT was enhanced by using Kalman filter which readjusts the characteristic of the thermoelectric generator.
