SIMULATION

This study models and simulates the wave energy potential along Nigeria’s coastline to evaluate its feasibility as a sustainable power source. With the nation facing persistent energy deficits and heavy dependence on fossil fuels, wave energy offers a clean and renewable alternative. Using real world oceanographic data from the Copernicus Marine Service (ERA5 dataset), key wave parameters significant wave height (Hs) and mean wave period (Te) were extracted and processed in MATLAB. A dynamic heaving point absorber Wave Energy Converter (WEC) model was then developed in Simulink to simulate power generation over a one year period (September 2024–September 2025). The simulation results show that a single 5-meter wide point absorber can generate approximately 13.88 MWh annually, with peak outputs during the summer months when wave activity is highest. The findings confirm that Nigeria’s wave climate, though moderate, is consistent and technically viable for decentralized, off grid energy applications, particularly for coastal communities and small industries. This research provides a quantitative foundation for future investment, policy development, and pilot projects aimed at integrating marine renewable energy into Nigeria’s sustainable energy mix.

The comprehensive study of high-frequency transmission lines, including stripline, microstripline, differential microstrip lines and differential straplines configuration is critical for advanced RF and microwave engineering education. Fundamentals of some transmission line phenomenon such as impedance matching, reflection coefficient and the effect of open and short circuits, relies greatly on practical hands-on experience alongside theoretical tools like the Smith chart. Furthermore, many academic institutions face challenges in providing laboratory systems that accurately represent high-frequency transmission line structures on common PCB substrates such as FR4. The absence of versatile and cost-effective experimental circuits limits students’ opportunities to explore and solve real-world transmission line problems, thereby hindering the development of essential engineering skills. This project aims to develop an integrated high-frequency transmission line experimentation systems for university laboratories, incorporating stripline, microstripline, differential microstriplines and differential striplines configuration on FR4 substrates. The system will facilitate direct measurement and analysis of transmission line behavior, enabling students to visualize various experiments, and investigate the proposed applications (e.g. open and short circuit effects, s-parameters,
transmission line as a filter etc.) within a controlled environment.
By linking theoretical concepts with practical experiments, specifically through the application of Smith chart and transmission line theory, this system will enhance RF engineering education, equipping students with the competence needed to address modern communication system challenges effectively
