With the Terahertz (THz) radiation, the portion of the electromagnetic spectrum covering the frequency range of 0.1-10 THz, corresponding to the radiation wavelengths from 3000 to 30 μm, is usually indicated. In recent years, a series of coherent sources and detection technologies have been developed covering the THz spectrum; hence far-infrared spectroscopy meets a renewed and great interest. This interest ranges from fundamental research that can now investigate the low frequency dynamics with appropriate tools, to technological applications that take advantage of the non-ionizing, non-invasive and penetrable characteristics of THz radiation.
However, THz spectroscopy is still in its infancy and a rapid increase in the efficiency and quality of spectroscopy techniques will develop in the coming years. In particular, for fundamental research the interaction of high-intensity THz pulses with matter is a hot topic, which requires an extension of the theoretical models of non-linear phenomena from optical frequencies to THz ones. Furthermore, among the numerous technological applications, a rapid and efficient THz imaging method remains to be implemented; this is not a trivial task that requires to overcome a series of technical limitations present today in THz technology.
In this special issue, we are planning to collect a series of research studies related to THz spectroscopy. They may include experimental investigations, theoretical models and methods of data analysis for signal extraction; as well as new sources of THz radiation, detection apparatus including methods of imaging and/or characterization of THz radiation.Prof. Dr. Renato Torre
Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
