Special Issue Information

Dear Colleagues,

Many electromagnetic problems such as large-scale scattering and radiation applications in complex domains’ multiscale structures modeling small and nano antennas, sensors, integrated circuits, etc.; and multiphysics problems require a discretization of the computational domain that yields billions of unknowns. Addressing this issue demands a multidisciplinary effort involving physics, computer science and architecture, advanced mathematical methods for integral equations, fast solvers, iterative methods, preconditioners, linear algebra, and big data. At the crossroads of these science fields, computational electromagnetics aim at solving accurately and rapidly the aforementioned problems, without heavy computational requirements. Also, efficient computer simulations have the potential of providing insightful knowledge that will eventually help improve the design and robustness of the products.

In this Special Issue, we call for contributions of innovative techniques that tackle challenging aspects arising in electromagnetic problems, including frequency vs. time domain, implicit vs. explicit formulation in time, absorbing boundary conditions vs. perfectly matched layers, structured/monoscale vs. unstructured/multiscale mesh, artificial intelligence, etc. We therefore cover the following topics:

  • Advanced numerical solvers for Maxwell problems
  • Artificial intelligence in computational electromagnetics
  • Computational electromagnetics for large-scale problems
  • Modeling and simulation of multiphysics problems in electromagnetics
  • Multiscale structures in electromagnetics
  • New emerging applications of electromagnetics

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. Applied Sciences 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.

We consider the problem of determining the dynamics of the electromagnetic field generated outside a ball whose charge changes depending on time. We are in conditions of perfect symmetry and the electric field is considered to be radial. This is not a simplification since, under such a hypothesis, the magnetic field does not develop. Thus, it is first necessary to find out the appropriate modeling equations. These are obtained by writing a suitable energy tensor that combines the classical electromagnetic stress-energy tensor with a special kind of mass tensor. The next step is to show that it is possible to solve Einstein’s equations by plugging the new tensor on the right-hand side. Interesting connections with some classical solutions related to black holes are finally established. Full article
