它不是默认主题之一，但您可以创建它：

\documentclass{beamer}
\useinnertheme[shadow=false]{rounded}
\usecolortheme{beaver}
\useoutertheme{sidebar}
\usepackage{tikz}

\definecolor{color1}{RGB}{94,124,114}% green-gray
\definecolor{color2}{RGB}{192,0,0}% red

\setbeamercolor{palette primary}{bg=color2,fg=white}
\setbeamercolor{palette secondary}{bg=color1,fg=red}

%\setbeamercolor{palette tertiary}{bg=color2,fg=color2}
%\setbeamercolor{palette secondary}{bg=color1,fg=color2}

\setbeamertemplate{footline}{}
\setbeamertemplate{navigation symbols}{}

\setbeamercolor{title}{bg=color2,fg=white}
\setbeamercolor{logo}{bg=color1,fg=white}

\setbeamercolor*{sidebar}{fg=white,bg=color1}

\makeatletter
\setbeamertemplate{headline}{%
    \begin{beamercolorbox}[wd=\paperwidth]{frametitle}
      \ifx\beamer@sidebarside\beamer@lefttext%
      \else%
        \hfill%
      \fi%
      \ifdim\beamer@sidebarwidth>0pt%  
        \usebeamercolor[bg]{logo}%
        \vrule width\beamer@sidebarwidth height \beamer@headheight%
        \hskip-\beamer@sidebarwidth%
        \hbox to \beamer@sidebarwidth{\hss\vbox to
          \beamer@headheight{\vss\hbox{\color{fg}\insertlogo}\vss}\hss}%
      \else%
        \vrule width0pt height \beamer@headheight%  
      \fi%
    \end{beamercolorbox}%
\begin{tikzpicture}[remember picture,overlay]
\coordinate (aux)
  at (\beamer@leftsidebar,-0.2\paperheight);
\coordinate (aux2)
  at (\beamer@leftsidebar,0);
\draw[
  line width=4pt,
  color2,
  rounded corners
  ]
  (\beamer@leftsidebar,0|-aux) --
  (aux2) --
  (\paperwidth,0|-aux2);
\node[
  outer sep=0pt,
  draw=color2,
  anchor=south,
  fill=white,
  text=black,
  circle,minimum size=14pt
  ] (numbu)
  at (aux) 
    {\insertsectionnumber};
\end{tikzpicture}%
}

\setbeamertemplate{background}{%
  \includegraphics[]{back}%
}

\addtobeamertemplate{sidebar left}{}{%
\begin{tikzpicture}[remember picture,overlay]
\coordinate (aux)
  at (\beamer@leftsidebar,.65\paperheight);
\draw[
  line width=4pt,
  black
  ]
  (\beamer@leftsidebar,0) -- 
  (\beamer@leftsidebar,0|-aux);
\node[
  outer sep=0pt,
  draw=black,
  anchor=south,
  fill=white,
  text=black,
  circle,minimum size=14pt
  ] (numbl)
  at (\beamer@leftsidebar,0) 
    {\insertframenumber};
\end{tikzpicture}%
}
\makeatother    

\logo{Logo}
\title[The title for the sidebar]{The title}

\begin{document}

\begin{frame}
\maketitle
\end{frame}

\section{Test section one}
\begin{frame}
\frametitle{Test frame}
test
\end{frame}

\section{Test section two}
\begin{frame}
\frametitle{Test frame}
test
\end{frame}

\section{Test section three}
\begin{frame}
\frametitle{Test frame}
test
\end{frame}

\end{document}

结果显示标题框和内部框：

图像中某些元素的含义不清楚；特别是侧边栏旁边圆圈内的数字的含义在问题中没有明确说明，所以我使用了部分编号和帧编号；可以适当修改这些元素以得到所需的结果。

back.png我用于模板的图像background只是原始背景的一个片段：
