Special Issue Information
Dear Colleagues,
The terahertz band (0.1 THz–10 THz), which has been barely exploited compared to the rest of the electromagnetic waves, has been receiving enormous attention around the world. Photonic devices exploiting this frequency band are set to become promising in a very diverse range of applications, such as biosensing, medical imaging, and 6G wireless communication technology, to name a few, due to their great potential in molecular label-free fingerprinting, non-ionizing properties, and broad spectral bandwidth. Among them, the realization of sensitive, high-speed, and high-efficiency micro-nano devices for wireless communication, terahertz integrated circuits, and miniaturized interconnects requires materials and structure designs with strong light–matter interactions. However, approaches for the generation, transmission, and conversion of terahertz electromagnetic waves are still limited. Therefore, novel materials and their micro-nano structures with strong terahertz response, extremely high electromagnetic confinement, and enhanced light–matter interaction are in urgent demand.
This Special Issue seeks reports on novel physical phenomena and mechanisms in new emerging materials (metals, semiconductors, two-dimensional materials, topological materials, etc.) for the emission, manipulation, and detection of terahertz electromagnetic waves, as well as the design and fabrication of micro-nano structures (cavity, metasurfaces, antenna, etc.) and devices for terahertz emission sources, modulators, detectors, and focal plane arrays for THz imaging.

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. Micromachines 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 2600 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.
