Special Issue Information
Dear Colleagues,
Terahertz (THz) waves have exhibited promising applications in imaging, sensing, and communications, especially for the next generation of wireless communications due to the large bandwidth and abundant spectral resources. The general THz applications strongly rely on efficient modulators for free-space or on-chip applications, especially in communications that would further require high-speed modulators and low-loss waveguides. With limited natural materials that have a high-efficiency response in the terahertz band, there are many difficulties in developing terahertz-functional devices and practical applications. Metamaterials (MTMs) are artificial composite materials with arrays of strongly scattering subwavelength “meta-atoms”, which have exhibited extraordinary performance to control free-space and on-chip wave propagation. Recently, THz MTMs have become a focus of active research in many fields, such as communication, radar, imaging, and biosensing. This Special Issue will present a collection of frontier studies, technologies, reviews, and perspectives on this rapidly evolving area and aims to address the key challenges and requirements across a broad range of THz MTMs and their applications.

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. Photonics 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 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
