Dear Colleagues,

Terahertz and millimetre wave imaging have become increasingly important because of potential benefits regarding security and defence, biomedical applications, brownout, whiteout, and airplane safety in general, law enforcement requirements, etc. Development of such imaging systems has lagged behind other spectral regions due to a lack of efficient and economical components. The purpose of this Special Issue is to update both system and component developments, as well as propagation models, in this emerging field. Papers on equipment and components, such as: (1) sources, detectors, focal plane arrays, modulators, etc.; (2) propagation through the atmosphere, walls, biological media, and other relevant media; (3) real time and non-real time imaging systems including image processing, 2- and 3-dimensional imaging; and (4) various applications pertinent to this spectral region.

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 submissions that pass pre-check are 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. Journal of Imaging is an international peer-reviewed open access monthly 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 1800 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.
