In a groundbreaking study published in the journal ‘Scientific Reports’ (translated from Arabic as ‘Reports of Science’), researchers have developed a sophisticated model to understand how heat and stress waves move through semiconductors with complex structures, like those used in advanced maritime sensors and communication devices. This work, led by Eman Ghareeb Rezk from the Mathematical Science Department at Princess Nourah bint Abdulrahman University, introduces a new way to analyze these materials under uncertain conditions, which is crucial for the maritime industry where equipment often faces unpredictable environmental stresses.
The research focuses on a type of semiconductor with a dual-porosity structure, meaning it has two different types of pores or voids within its material. These semiconductors are often used in maritime applications for their ability to handle high-frequency signals and withstand harsh conditions. The study introduces stochastic, or random, variations into the model to simulate real-world uncertainties, such as changes in temperature and pressure that ships and offshore platforms might encounter.
According to the study, the model shows that increasing the porosity of the material can enhance wave attenuation, which means it can absorb and reduce the impact of stress waves more effectively. This is particularly important for maritime structures, where reducing stress can prevent failures and extend the lifespan of equipment. The research also highlights that higher phase-lag parameters delay the propagation of temperature and stress, giving engineers more time to respond to potential issues.
One of the key findings is the significant influence of the two-temperature coupling parameter on the magnitude and spread of thermal variance. This means that the way heat is distributed within the material can vary greatly, which is crucial for designing reliable and efficient maritime sensors and communication devices. As Dr. Rezk explains, “The variance amplitudes remain within realistic physical bounds for semiconductor materials, confirming the model’s stability and practical relevance.”
For the maritime industry, this research opens up new opportunities for designing more robust and efficient semiconductor-based technologies. By understanding how these materials behave under uncertain conditions, engineers can develop better sensors, communication devices, and structural components that can withstand the harsh maritime environment. This could lead to improved safety, reliability, and performance of maritime equipment, ultimately benefiting the entire industry.
In summary, this study provides valuable insights into the behavior of semiconductors under stochastic conditions, which is essential for the maritime sector. By leveraging these findings, the industry can enhance the design and optimization of critical components, ensuring they perform reliably in the face of unpredictable environmental stresses.
