The purpose of this study is analytical studying Initial-Boundary-Value Problem for the novel format of Maxwell’s equations in SI units. A modified version of the Evolutionary Approach to Electromagnetics (EAE) used herein. The problem is considered for the causal electromagnetic oscillations excited by a given external rectangular pulse signal, J (r, t) , in a hollow cavity with lossy metallic walls. The cavity volume V is finite and closed by a singly connected surface S with none of its inner angles exceeds . Physically, cavity walls are lossy (completely or partially). Graphical results are exhibited demonstrating that the electromagnetic oscillations inside the cavity with metallic surface satisfy the causality principle., Bu çalışmanın amacı, SI birim sisteminde yeniden yazılmış Maxwell denklemlerine ilişkin başlangıç-sınır-değer problemine analitik bir çözüm sunmaktır. Çalışmada Elektromanyetik Teoriye Evrimsel Yaklaşım’ın modifiye edilmiş bir versiyonu kullanılmıştır. Problem, kayıplı metalik yüzeylere sahip boş bir kaviteye verilen dikdörtgen J (r, t) darbe sinyalleri, tarafından uyarılan nedensel elektromanyetik osilasyonlar için düşünülmüştür. Kavite hacmi, V, sonludur ve S yüzeyinin iç açılarından hiçbirinin π 'den büyük olmadığı pürüzsüz bir S yüzeyiyle kapatılmıştır. Fiziksel olarak yüzey (tamamen ya da kısmen) kayıplıdır. Kayıplı yüzeylere sahip kavite içerisindeki elektromanyetik osilasyonların nedensellik prensibini sağladığını gösteren grafiksel sonuçlar sergilenmiştir.

Professor Oleg A. Tretyakov is recognized in the field of radiophysics as the founder of the Evolutionary Approach to Electromagnetics (EAE). His analytical time domain approach which was acknowledged as an alternative to the method of complex amplitudes successfully applied to cavity and waveguide problems. In his final years, he proposed a novel format of Maxwell’s equations in SI units where electric and magnetic field strength vectors have a common physical dimension of inverse meter. In this article, we pay special tribute to his exceptional career and contributions to science and extend his last work to derive a novel format of the wave equation in SI units.

The year 2023 represents a milestone for our country, our academy, and for our journal. The Republic of Türkiye will celebrate its centennial, the Turkish Naval Academy (TNA) will celebrate its quarter-millennial, and the Journal of Naval Sciences and Engineering (JNSE) will celebrate its vicennial in 2023. Undoubtedly, the historical intersection is a source of praise and pride for our academy and for our journal. 99 years ago, the Turkish nation created an epic of independence under the leadership of Gazi Mustafa Kemal Atatürk and his comrades in the War of Independence. The 100th anniversary of the Republic will be celebrated in 2023 to cherish the deep-rooted memory of our struggle for independence. Founded in 1773 by Mustafa III, the 26th Sultan of the Ottoman Empire, the Imperial School of Naval Engineering (Mühendishane-i Bahr-i Hümâyûn), considered the first engineering school of the Empire, became the foundation of both the TNA and the Istanbul Technical University (ITU). TNA and ITU have special positions in terms of Turkish modernization history as the institutions where engineering and technical education have continued since the Ottoman period with their 249 years of distinguished history. 2023 will mark these exceptional institutions’ 250th anniversary. 2023 will also mark the 20th anniversary of the international journal of the TNA, i.e., JNSE. The journal aims to provide a scientific contribution to the theory and applications of naval sciences and engineering and share knowledge in relevant fields since its first issue in 2003. As we are entering this historically significant year, it is an honor and privilege for me to have been appointed as the Editor-in-Chief (EIC) of the scientific journal of our prestigious 250-year-old academy. As an Editorial Board Member since 2013, as well as an Editor in both 2018 and 2019, and as an Administrative Board Member of the Naval Sciences and Engineering Institute from 2013 to 2022, I have seen the continued improvement that JNSE has experienced. I inherit the role of Editor-in-Chief of the JNSE at a special time when our journal has been included within the scope of the ULAKBIM TR Index. The journal must, first and foremost, continue to provide a contribution to science and engineering in fields aligned with the areas of interest of the JNSE, e.g., electrical and electronics engineering, naval/mechanical engineering, naval architecture and marine engineering, industrial engineering, computer science and engineering, and basic/social sciences. In the meantime, we will do our best to make our journal ready to be a candidate to be indexed in Science Citation Indexes. Raising the quality of the accepted papers by introducing strict review criteria will be instrumental in achieving this goal by increasing the impact of the journal. To this end, we recently applied to join Crossref as a member under the sponsorship of TUBITAK ULAKBIM DergiPark, and consequently, the JNSE will be able to provide a DOI (Digital Object Identifier) for accepted papers submitted after 1 September 2022 via the 'DergiPark' online system. With the new structure of JNSE’s Editorial Board, when a manuscript is submitted, the EIC assigns it to the appropriate Editorial Board Member based on the main topic area of the manuscript. The assigned Member should assign a minimum of two reviewers to evaluate the manuscript. He/she is expected to make his/her own independent review of the manuscript and, once the reviewers have completed their evaluation, he/she submits a recommendation to the EIC. The EIC checks for consistency among the recommendations, typically accepts the recommendation of the assigned Editorial Board Member and then communicates to the corresponding author the final decision together with the comments of the reviewers. We are therefore starting with a smaller, more flexible, and resourceful Editorial Board, dedicated to this purpose. I hope that with the other editors, we can push JNSE to a more competitive position within the field; a position that it rightly deserves. I also take this opportunity to introduce Onur USTA who will be working with me as the Assistant Editor-in-Chief. I would like to thank all the editorial team members and look forward to working with them. The success of any journal is built on the support of the contributors, the reviewers, the editors, and the publication staff. I look forward to receiving your ideas for making JNSE more valuable for our community. We welcome your original contributions to our issues that will be published in this historical intersection, where the centennial of the Republic, the sestercentennial of the TNA, and the twentieth year of the JNSE meet.

In the International System of Units (SI), distinct physical dimensions were assigned to the electric ( $E$ ) and magnetic ( $H$ ) fields as volt-per-meter and ampere-per-meter, respectively. To save the dimensional balance in the standard Maxwell’s equations (MEs) in SI units, a pair of free-space constants, $\epsilon _{0}$ and ${\mu } _{0}$ , with their dimensions of farad-per-meter and henry-per-meter were installed heuristically. Eventually, every quantity that participated in each ME in SI units has an individual physical dimension distinct from the other terms therein. This situation hampers the control of the dimensional balance in the processes of analytical manipulations with the MEs during the theoretical studies. Reformatting the free-space constants is performed in this article so that one new constant is obtained with its dimension of volt, and the other one has its dimension of ampere. These gave a handle to scale the electric and magnetic fields appropriately. Ultimately, the new fields are obtained with their common dimension of inverse-meter. Meanwhile, the standard differential procedures $\epsilon _{0}\frac {\partial }{\partial t}$ and ${\mu } _{0}\frac {\partial }{\partial t}$ from MEs are obtained in their simple common format of $\frac {\partial }{c\,\partial t}$ , where $c$ is the speed of light. The MEs in the novel format are exhibited for the fields in the free space, plasma, and dielectrics. The content of this article is destined for the researchers who deal with theoretical studies in electrodynamics, and the level of content is appropriate for and realizable by recent graduates, M.Sc. and Ph.D. students, and professionals.
