Zhang, H. (author)
In recent decades, dielectric lens antennas have been more and more adopted and developed for sensing and imaging applications at sub-millimeter (sub-mm) wavelengths because they can achieve high gain while keeping their physical size and weight acceptable at these wavelengths. More recently, as low-loss and low-cost lens materials have become...

Pascual Laguna, A. (author)
The mysteries of the early Universe are largely enshrouded in dust, product of the violent process of star formation. Due to the vast distances of our Universe, infrared light emitted by the heated dust back in those early stages can still be observed today, which has been observed to contribute to about half of the total cosmic background...

The fifth generation of mobile communication poses challenges in the form of increased data volume, network scalability and efficient network operation. An important part in meeting these requirements is the use of the mm-wave frequency range, enabling the use of a wide bandwidth and therefore the desired high-data rates. However, a challenging...

The expanding demand for high-speed wireless communications is pushing current networks and systems close to their limits. The use of sub-THz bands, where large bandwidth is available, is pointed out as one of the key strategies to cope with the huge amount of data transfer in the next Beyond 5G and 6G communications generations. Despite the...

In the design of millimeter and sub-millimeter wave radiometric imaging systems a persistent goal is the increase in the speed of acquisition of the image while maintaining a high sensitivity. Typically, the highest sensitivity is achieved by cryogenically cooling the detectors, specifically in astronomical applications. However, for the purpose...

The Terahertz gap is the portion of the spectrum lying between 300 GHz and 3 THz. The initial development of Terahertz technology was driven by Space-based instruments for astrophysics, planetary, cometary and Earth science. However, in recent years, the interest of Terahertz science has been rapidly expanded due to the emergence of new...
