Recent Advances in Wireless Power Transfer and Wireless Sensing

Dear Colleagues,

The possibility of obtaining the far-field or near-field control of electromagnetic wave has a profound influence on optical science and information communication. Recently, wireless power transfer (WPT) and wireless sensing (WS) have triggered immense research interest in a range of practical applications, including high-sensitivity sensors and stable charging without cables. Modern-day interest in WPT and WS relying on magnetic resonance and near-field electromagnetic coupling have directly resulted in tremendously exciting and ground-breaking applications. At present, the ground-breaking idea of using near-field resonance for WPT and WS has boosted the development of the related fields. Moreover, with the help of novel physical concepts, modern WPT and WS technologies have been significantly developed. WPT and WS based on new physical mechanisms and metamaterials are expected to produce next-generation wireless devices that break through the existing technologies and promote the development of devices and industries.

We invite the submission of original research, review, mini review, perspective articles on themes including, but not limited to:

• Various WPT and WS technologies, including radiation mechanism and near-field coupling mechanism.
• Metamaterials-based WPT and WS systems.
• Circuit topology optimization for WPT and WS.
• WPT and WS controlled by the external excitation, such as voltage and time-domain signal.
• WPT and WS based on topological photonics, such as topological edge states, corner states, and novel topological skin effect.
• WPT and WS based on non-Hermitian physics, including coupled perfect absorption, exceptional points, high-order systems, and circuit systems with synthetic dimensions.
• WPT and WS with novel localized states, such as anapole modes, hyperbolic high-k modes and bound states in the continuum.
• Nonlinear-effect-promoted WS and robust WPT.
• Other related near-field areas: wireless communications, magnetic resonance imaging, magnetic shielding, and near-field routing.
• Other related WPT and WS areas: optics and acoustics.

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.
