# placing three images, two side by side both below the first one in a twocolumn class

I would like to have something like on the picture for the layout of three images. I am in twocolumn class and I know or how to place two images one above the other or side by side but not how to do both operations at the same time. Particurarly I tried 'inserting' the code part wrote on :

Placing two images side by side in a twocolumn document (see the accepted answer)

into

 \begin{figure}[h]
\centering
\begin{subfigure}[b]{0.49\textwidth}
\includegraphics[width=0.96\linewidth,clip]{apparatusXDET}
\caption{}
\label{fig:1}
\end{subfigure}


HERE, at this point I inserted the linked part

  \end{figure}


Unfortunately it says that two packages (subcaption and subfigure) are not compatible one with each other. Anyone has a idea how to do it?

:

 \documentclass[twocolumn,prl,nobalancelastpage,aps,10pt]{revtex4-1}
\usepackage{subcaption}
\begin{document}
\begin{figure}
\centering
\begin{subfigure}[b]{0.9\linewidth}
\includegraphics[width=\linewidth]{cu}
\caption{Too much coffee.}
\end{subfigure}
\label{fig:coffee3}
\begin{subfigure}[b]{0.3\linewidth}
\includegraphics[width=\linewidth]{cu}
\caption{Coffee.}
\end{subfigure}
\begin{subfigure}[b]{0.3\linewidth}
\includegraphics[width=\linewidth]{cu}
\caption{More coffee.}
\end{subfigure}
\caption{The same cup of coffee. Multiple times.}
\end{figure}
\end{document}


try this on your code. On mine twocolumns class document worked well. You need just to play with the WIDTH parameter to get what you want. Thanks goes to :
