Terahertz Optics, Beam Shaping and Imaging

Dear Colleagues,

Everybody who have tried to conduct an experiment with terahertz radiation knows how special and exceptional it is. No matter which sources and detectors we use, in many cases something unexpected may be found giving us, as curious researchers of world, the pleasure of discovering new peculiarities and then understanding new phenomena. Terahertz frequencies still lacking in efficient, easily accessible and inexpensive emission and registration components, however, in addition, there is a tremendous need of cunning forming and redirecting beams, their focusing and shaping in a desired way. This special issue is related to different optical elements used for terahertz frequencies, various optical setups enabling forming terahertz images and diverse methods of shaping terahertz beams.

Having great honor and pleasure of editing this special issue, I cordially invite you to submit your original research on all related topics, including:

• Terahertz optical elements—reflective, refractive, and diffractive;
• Metamaterial and subwave optics;
• Terahertz imaging;
• Terahertz beam shaping;
• Terahertz emitters and detectors.

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences 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 2400 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.
