Special Issue Information

Dear Colleagues,

The start of the 21st century marked a remarkable advancement in high-frequency microelectronics and the advent of the microwave and millimeter-wave radar systems on chips. This has spurred exponential growth in the research and development of new applications in sensing and imaging, including vehicular guidance, non-destructive testing, biomedical diagnostics, monitoring, security, surveillance, non-destructive testing, and inspection.

This Special Issue aims to highlight original research and informative reviews of the latest advances in the fields of radio-frequency (RF), microwave, and millimeter-wave sensing and imaging with a focus on emerging devices and systems amenable to portable, vehicular, and wearable deployment.

Topics of interest include but are not limited to the following:

  • Microwave and millimeter-wave sensors and systems;
  • Microwave and millimeter-wave imaging systems and antennas;
  • Microwave signal processing for target and fault detection, classification, and identification, as well as target tracking;
  • Advancing microwave and millimeter-wave image-reconstruction algorithms toward real-time processing, the processing of sparse and randomly sampled data, data fusion, etc.;
  • Challenges and solutions for high-frequency sensing and imaging on mobile and wearable platforms;
  • Microwave sensing and imaging in biology and medicine, environmental monitoring, non-destructive testing, and new emerging applications;
  • Radiometry in microwave sensing and 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 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. 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.

Fill level control is one of the strict checks required when inspecting industrially packaged products. The purpose is both to ensure the content conformity according to the declared label information and to preserve the reliability of brand trust, strongly influenced by the customer’s evenness perception of the marketed items. To this aim, choosing the right technology is not an easy task: content and packaging material properties are essential to establish the suitability of a product to the fill level machine type. In this paper, we propose a novel approach, based on microwaves, to address this issue. The designed microwave inspection system consists of two Vivaldi antennas working between 1 and 18 GHz. We show its applicability to water, oil and alcohol-based products moving on conveyor belts at production speed. The performed experiments demonstrate good accuracy and efficiency of level classification and fault rejection in real-time processing. Full article
