Detectors made from sub-micron-sized bridges of the high- Tc superconductor Y–Ba–Cu–O have unique properties useful for the detection of THz radiation, namely evidence of a detector response with an additional sensitivity to the direction of the electric field of short THz pulses when used without a transport current in the so-called “zero-bias” regime. In order to examine the influence of the antenna design on the detector response, we have conducted electromagnetic simulations and performed experiments at a synchrotron light source and with a photomixing setup as sources for short THz pulses. In this paper, we evaluate a narrow-band double-slot antenna as well as a broadband log-spiral antenna design

Scope

SUST invites manuscripts that document the state-of-the-art in superconductor terahertz science and applications. Terahertz technology in the frequency range 0.3–30 THz has attracted much interest owing to potential applications in many fields for astronomy, medical diagnostics and biology, quantum communications, security, defense, non-destructive testing, and so on. Terahertz frequency range lies in between microwave and optical ranges, and shares some characteristics of both regimes. The nature of terahertz waves that bridges electronics and photonics has made the terahertz science and technology an important area of research. Terahertz devices with better performance, such as e.g. narrow-band high-brightness sources, or highly-sensitive broad-band detectors are now available. Terahertz technology is presently employed in space science to explore the universe, as well as for many terrestrial applications.

Our special issue aims at highlighting all developments in the broad area of superconductor THz science and applications. We will consider theoretical, numerical, and experimental papers that cover but are not limited to the following topics:

• Novel THz sources and detectors
• THz imaging and spectroscopy techniques and systems
• New THz materials and devices
• New phenomena in superconductors probed by THz waves
• Nonlinear THz interactions with superconductors
• Development of THz devices, components, and systems
• Applications of THz radiation in astronomy, physics, life sciences, and industries
