Special Issue Information

Dear Colleagues, 

This Special Issue, titled “Recent Advances in Electromagnetic Devices, 2nd Edition”, will explore the latest developments in the field of electromagnetic technology, focusing on innovations in design, materials, and applications. Central themes of this Special Issue include the optimization of device efficiency, miniaturization, and integration with other technologies. Key advancements within this field will be highlighted, such as the following:

  • Metamaterials, which enable novel properties and functions not found in natural materials, leading to breakthroughs in antenna design, cloaking, and electromagnetic shielding;
  • The momentum gained by wireless power transfer, allowing for efficient energy transmission over short and long distances with applications in consumer electronics and electric vehicles;
  • Electromagnetic actuators and sensors, which have the potential to improve robotic systems, medical devices, and aerospace engineering;
  • Aspects of optical devices and photonic devices such as lenses, mirrors, microscopes, fiber optics, imaging, sensing, lasers, solar energy harvesting, photodetectors, and biomedical research.

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. Micromachines 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 2100 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.

by Jian Wang, Jianyuan Wang, Jinbao Chen, Chukang Zhong and Yuankui Shao
Micromachines 2026, 17(1), 5; https://doi.org/10.3390/mi17010005 (registering DOI) - 20 Dec 2025
Abstract
This paper presents the design, implementation, and experimental validation of a high-precision angular measurement system based on a round inductosyn. Dedicated hardware circuits, including excitation, signal conditioning, and resolver-to-digital conversion modules, together with software algorithms for coarse–fine data fusion and linear interpolation-based error [...] Read more.
This paper presents the design, implementation, and experimental validation of a high-precision angular measurement system based on a round inductosyn. Dedicated hardware circuits, including excitation, signal conditioning, and resolver-to-digital conversion modules, together with software algorithms for coarse–fine data fusion and linear interpolation-based error compensation, are developed to achieve accurate and stable angular measurement. Experimental results obtained from repeated measurements over a full rotation demonstrate reliable system operation and effective suppression of nonlinear errors. After compensation, the residual angular error is limited to within ±3″, while measurement consistency across repeated experiments is significantly improved. The output angle exhibits good continuity and stability, confirming the feasibility and effectiveness of the proposed system for high-precision servo control and aerospace attitude measurement applications.

A super-wideband transparent antenna (SWTA) with wide axial ratio bandwidth (ARBW) featuring an enhanced ground plane and microstrip feeding is proposed. The antenna has planar dimensions of 0.20λ0 × 0.20λ0 × 0.003λ0 at its lowest frequency of [...] Read more.
A super-wideband transparent antenna (SWTA) with wide axial ratio bandwidth (ARBW) featuring an enhanced ground plane and microstrip feeding is proposed. The antenna has planar dimensions of 0.20λ0 × 0.20λ0 × 0.003λ0 at its lowest frequency of 1.33 GHz. The antenna is fabricated from a combination of PET and metal oxide thin films, which together enable its flexibility and transparency. The L-shaped strips attached to the ground perturb the electric field in the slot, exciting a pair of orthogonal modes and resulting in circular polarization. The proposed antenna demonstrate high performance with an impedance bandwidth of 182% (1.33–28.52 GHz), an axial ratio bandwidth of 66% (3.88–7.73 GHz), and attain a peak gain of 11.5 dBi. Moreover, with an optical transparency exceeding 90%, this design is a flexible, transparent, super-wideband (SWB) antenna capable of high data rates, easy integration, and beyond-visual-line-of-sight (BVLOS) operations.
