Special Issue Information
Dear Colleagues,
The THz region of the electromagnetic spectrum, which until recently was referred to as a “THz gap”, is nowadays considered as the “last frontier” due to the remarkable recent progress in the development of high-performance radiation sources, detectors, and other components operating in this frequency range that have stimulated the emergency of many novel and prospective applications in a broad scientific and technological field. Nowadays, THz radiation (both coherent and broadband) is used for imaging, sensing, medical diagnostics, materials processing, communications, advanced spectroscopic techniques, etc., to name but a few of the most notable research areas. In any system utilizing THz waves, the optical elements for shaping and manipulating the THz wave beam are indispensable components. This Special Issue is devoted to their fundamental principles and the current state-of-the-art in their development, investigation, manufacturing, and usage.
Areas of interest include (but are not limited to) the following main topics:
- Fundamentals and physical principles of the THz optics
- Terahertz sources and detectors
- Focusing lenses for THz waves
- Diffractive THz optical elements (e.g., beam homogenizers), collimators, beam splitters, reflectors, polarizers, attenuators, filters
- Computational design of THz optical and quasi-optical elements
- Materials (including metamaterials) and advanced technologies (e.g. 3D-printing technology, laser treatment, etc.) for precise fabrication of THz optical components
- Production of optical elements for THz systems (scanners, cameras, imaging, and inspection devices)
You are kindly invited to contribute to this Special Issue and present your latest results in this broad and rapidly expanding field of THz science and technology.
