Special Issue Information

Dear Colleagues,

The Guest Editors of this Special Issue are seeking submissions of both review and original research articles related to electromagnetism and symmetry.

Electromagnetic fields and waves play a pivotal role in the industrial repository, especially in the field of electromagnetic (EM) non-destructive testing (NDT). The EM technique interrogates samples with electric and magnetic fields to observe the EM properties of the material, particularly conductive and magnetic permeable materials.

There exist several variants of EM testing methods, including eddy current testing (ECT), magnetic flux leakage (MFL), remote field testing (RFT), magnetic particle inspection (MPT), alternating current field measurement (ACFM), alternating current potential difference (ACPD), and direct current potential drop (DCPD). Owing to its sensitivity to small discontinuities, EM testing has been widely applied in object recognition, health monitoring, surface fatigue inspection, and measuring the inhomogeneity of metallic properties including electrical conductivity, magnetic permeability, and the thickness of the sample.

We encourage researchers to apply a wide range of electromagnetic methods, and, in particular, to develop theoretical models and applications including the concept of symmetry. This Special Issue welcomes contributions from, but not limited to, the following fields: electromagnetism and symmetry, electromagnetics, computational electromagnetics, and electromagnetic modeling.

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. Symmetry 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 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.

In this article, a novel hybrid method of multilevel kernel degeneration and adaptive cross approximation (MLKD-ACA) algorithm with integral kernel truncations is proposed to accelerate solving integral equations using method of moments (MoM), and to simulate the 3D eddy current nondestructive evaluation (NDE) problems efficiently. The MLKD-ACA algorithm with an integral kernel-truncations-based fast solver is symmetrical in the sense that: (1) the impedance matrix, which is generated by the MoM representing the interactions among the field and source basis functions, is symmetrical; (2) the factorized form of the integral kernel (Green’s function) resulted from degenerating it by the Lagrange polynomial interpolation is symmetrical; (3) the structure of the truncated integral kernel for the interactions among the blocks, which ignores the trivial ones of the far block pairs, is symmetrical using the integral kernel truncations technique. The impedance variations predicted by the proposed symmetrical eddy current NDE solver are compared with other methods in benchmarks to show the remarkable accuracy and efficiency. Full article
