Air Chemistry in Hypersonic Shock Layers: Understanding Extreme Aerodynamic Environments
When a vehicle travels at hypersonic speeds—typically defined as Mach 5 and above—it encounters extreme aerodynamic conditions that fundamentally alter the behavior of the surrounding air. One of the most critical phenomena in hypersonic flight is the formation of a shock layer, a thin region of highly compressed, heated gas that forms near the nose […]
Plasma Antennas: A New Frontier in Reconfigurable Wireless Communication
In the ever-evolving world of wireless communication, the demand for adaptive, high-performance, and interference-resistant antenna systems continues to grow. Indeed, the electromagnetic spectrum is becoming increasingly crowded, and future communication systems should be able to quickly switch to a different frequency or even a different band. Traditional metal antennas have been the backbone of communication […]
The Potential of Plasma-Assisted Combustion for Next-Generation Engines
When we think of combustion, the image that typically comes to mind involves flames fueled by a mixture of air and traditional fuels like gasoline, kerosene, or natural gas. This process has been the backbone of applications from home cooking to power plants to propulsion systems for aircraft and rockets for over a century. However, […]
Low-Temperature Plasma Science Driven by Practical Applications
Although all scientific discoveries eventually find their applications in technologies, some areas of science are driven primarily by our curiosity and our quest to understand the world we live in. However, many scientific discoveries and developments, and even entire scientific areas, are prompted directly by practical needs. The science of low-temperature plasmas and electric discharges […]
Tunable and Reconfigurable Radio-Frequency and Microwave Systems Through Plasma Technology
With the explosive development of communication systems, the electromagnetic spectrum in the radio-frequency (RF) and microwave ranges is becoming increasingly congested. Additionally, in military applications, communication and guidance devices can be jammed or damaged by electronic warfare systems. To overcome these challenges, RF systems should acquire the capability to be rapidly switched to a different […]
The Role of Plasma Science in Shaping the Future of Aerospace Engineering
When I first delved into the fascinating world of plasma physics and plasma chemistry, I was aware, of course, that high-temperature plasmas are essential for controlled nuclear fusion, and low-temperature plasmas of electric discharges are used in fluorescent lights and in microchip fabrication systems. However, I could not have imagined that this field could have […]
