\begin{abstract}
These pages provide the necessary instructions for authors to prepare their 2-page digest for NUMELEC 2024, which will be held in Paris in July 2024. We recommend you read and follow the instructions carefully to ensure readability and uniformity of the published papers. Papers not following the instructions or received after the submission deadline of January 15, 2024 may be refused.

\section{GENERAL INFORMATIONS}
Submission of papers to NUMELEC 2024 will take place in two steps. Papers submitted will be reviewed separately during these two steps. The first step is the submission of digests that will be reviewed for presentation and will be included in the proceedings of the conference.
Subsequently, authors of accepted papers will be invited to submit an extended version of their papers either to EPJ Applied Physics,or to COMPEL. They will be selected according to the usual criteria of these journals. Papers not submitted to the Conference will be excluded from this selection.
Digests should be submitted online, via the NUMELEC website \url{http://numelec2024.sciencesconf.org}.

Each digest should include a brief introduction not exceeding 100 words. The complete digest must not exceed 2 pages presented on 2 columns, including figures, tables and references. 

\section{TECHNICAL INFORMATIONS}

These instructions have been prepared according to the style and format that must be used for the preparation of the digest. Digests will be submitted in PDF format. 

\subsection{Format}

Paper size A4 (297x210 mm) is required. When formatting your page, place your top and bottom margins to 20 mm and the left and right margins to 18 mm. 
Do not number the pages.
The width of the columns is 84.5 mm, the space between columns is 5 mm. Justify your columns to the left and right. Use 3.5 mm for paragraph indent. On the last page of your paper, try to adjust the length of the two columns so that they end at the same level on the page.
 
\subsection{Character Sizes}

Use a serif type font, such as Times New Roman. The character sizes used in these instructions are listed in the table below. We recommend that you follow them wherever possible.

Line spacing: Use single line spacing. Titles, authors’ names, affiliation, section headings, figures, tables, legends and equations must be centered and separated by blank lines. 

Section numbering: Section titles must be numbered in Roman numerals: I, II, etc. Titles of sub-sections must be numbered in capital letters: A, B, etc. If it is unavoidable, apply the same style to “sub-sub-section” titles as “sub-section” titles, but attach them to the text (do not leave blank lines). 

\subsection{Equations}

When numbering the equations, put the number in parentheses and align it with the right margin as in example \eqref{eq:eq1}

\begin{equation}
\nabla \times E=-\partial _{t}B
\label{eq:eq1}
\end{equation}

Make sure that the symbols in your equation have been defined previously to the equation or that their definition follows immediately after the equation.

\subsection{Figures and tables}

Figures and tables should be inserted in the text. The figure caption must be placed at the bottom of the figure, as shown in Fig.~\ref{fig:fig1}; the table title must be put above the table, as shown in Table~\ref{tab:tab1}. When referring to a figure, use Fig. Number the tables using Roman numerals, as shown in Table~\ref{tab:tab1}.
