An efficient directive antenna is described that can be used to realize essentially non
dispersive links over extremely large bandwidths. The antenna is a significantly enhanced …

Dielectric lens antennas are attracting a renewed interest for millimeter-and submillimeter-
wave applications where they become compact, especially for configurations with integrated …

Starting from a challenge in the early 1990s to develop a highly shaped beam dielectric lens
antenna for a pilot 150 Mb/s cellular mobile broadband system operating in the 60-GHz …

In millimeter and submillimeter-wave radiometric imaging systems, a persistent goal is the
increase in the speed of acquisition of the image while maintaining a high sensitivity …

Integrated superconducting spectrometer (ISS) technology will enable ultra-wideband,
integral-field spectroscopy for (sub) millimeter-wave astronomy, in particular, for uncovering …

This paper presents the first demonstration of the applicability of the leaky lens antenna
concept at THz frequencies. The antenna is integrated with a Kinetic Inductance Detector, so …

In most communication scenarios, antennas are often required to achieve broadband and
directional radiation, and beam squint with frequency is unfavorable for broadband signal …

As digital circuits are approaching the limits of Moore's law, a great deal of effort has been
directed to alternative computing approaches. Among them, the old concept of optical signal …

Optically pumped THz sources generate power in GaAs semiconductors via
photoconductive interaction mechanisms over very large bandwidths. However, they are …

This paper describes the combined Dutch efforts toward the development of large wideband
focal plane array receivers based on kinetic inductance detectors (KIDs). Taking into …
