Special Issue Information
Dear Colleagues,
Since the beginning of the study of reconfigurable including metasurface structures, there has been a lot of research on RISs (reconfigurable intelligent surfaces) to utilize them for wireless communication. RIS research initially started with IRSs (intelligent reflecting surfaces), which centered on reflection characteristics, and recently expanded to IOSs (intelligent omni surfaces), which have both transmission and reception characteristics. RISs are used in 5G or 6G mobile wireless communication environments to overcome communication performance degradation in shaded areas, especially in indoor propagation environments. Despite all the research being conducted on RISs, there still exist several technical issues. For example, how to sense and estimate the channel state information, how to accurately model the EM characteristics of RISs in the channel, how to implement cost-effective and controllable RISs, how to implement the proposed active RISs to overcome multiplicative fading in RIS channels, and how to efficiently implement the RIS control board, all remains contentious issues.
In this Special Issue, we will cover a variety of research findings for implementation in real-world wireless environments to address the technical challenges of RISs.
In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:
- Hardware implementation of RISs;
- Implementing RISs with sensing and control;
- Active or hybrid RIS structure;
- Measurement system of RISs;
- Wideband or multifunctional RISs;
- Transparent RISs;
- Codebook implementation of RISs;
- Power-saving or -harvesting RISs.
I look forward to receiving your contributions.

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. Electronics 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.
