The terahertz band (THz) is today one of the most attractive research topics in electromagnetics. Historically, this region that goes from 100 GHz to 10 THz has remained largely unexplored due to the lack of efficient sources and detectors, limiting its application to specific niches such as astronomy and spectroscopy. However, this situation has turned around thanks to the development of cheap emitters and receivers capable of operating at room temperature. All these factors together have paved the way for endless applications in security, defense, biomedicine, chemistry, space, food industry, etc.

The development of THz technology has coincided in time with the irruption of metamaterials and plasmonics. Both disciplines focus on controlling the propagation of electromagnetic waves and offer possibilities that go beyond the natural media. In recent times, they have evolved towards more compact structures known as metasurfaces giving a new impetus in both basic science and applied research. The seminar will discuss the latest advances in THz devices developed in the Antenna Group – Teralab at the Public University of Navarra: ultra-compact invisibility cloaks, epsilon-near-zero graded index lenses, thin film sensing metasurfaces, etc.
