Wireless Sensing and Intelligent Reflective Surfaces

Introduction:

The total installed base of Internet of Things (IoT)-connected devices, such as sensors in wireless sensor networks (WSN), is projected to amount to 75.44 billion worldwide by 2025, a five-fold increase in ten years. This transition will present a formidable challenge as wireless networks are hitting their physical capacity limits. Therefore, it is of utmost importance to develop radically new solutions to support this ever-increasing number of connected devices.

Intelligent reflecting surfaces (IRS) can be incorporated with environmental objects and can perform operations such as reflect, refract, absorb, polarization adjust, and modulate data onto the received signals in order to guarantee high accuracy, long-range, and large-scale wireless sensing. Recent advances in the development of artificial materials with specific electromagnetic properties have demonstrated that this breakthrough idea can become a scientific reality.

This Special Issue welcomes both reviews and original research articles in the field of wireless sensing through IRS, following the submission guidelines of Sensors, within the remit of this Special Issue call. Topics include but are not limited to planar/flexible/wearable IRS for wireless sensing with applications in agriculture, smart homes/vehicles/drones, and medical diagnostics. Microwave imaging techniques using IRS are also of interest. We invite and encourage your participation to this Special Issue.

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. Sensors 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 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.
