具有不同层和波的图表

我怎样才能绘制附图TikZ？

\documentclass[border=10pt,tikz]{standalone}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,positioning,arrows.meta,decorations.markings,shapes}

\begin{document}
\begin{tikzpicture}[line width=.2mm,font=\scriptsize]
\draw[fill=black!50!] (0,0) rectangle (3,2);
\draw[fill=white] (.5,.5) rectangle (2.5,1.5) node [pos=.5] {Layer 3} ;
\draw[fill=black!20!] (0,2) rectangle (3,5);
\draw[fill=white] (.5,3) rectangle (2.5,4) node [pos=.5] {Layer 2} ;
\draw[fill=black!35!] (0,5) rectangle (3,7);
\draw[fill=white] (.5,5.5) rectangle (2.5,6.5) node [pos=.5] {Layer 1} ;

\draw[dashed] (3,7) -- (11,7);
\draw[dashed] (3,5) -- (11,5);
\draw[dashed] (3,2) -- (11,2);

\node at (1.5,-.5) {$\begin{array}{c}
\text{Material}\\
\text{Profile}
\end{array}$};

\node at (5,-.75) {$\begin{array}{c}
\text{Shortl}\\
\text{Wavelength} \\
\sim \lambda_{R1}
\end{array}$};

\node at (8,-.75) {$\begin{array}{c}
\text{Longer}\\
\text{Wavelength} \\
\sim \lambda_{R2}
\end{array}$};

\draw[->,line width=.3mm]  (5,7) -- (7,7);
\draw[->,line width=.3mm]  (5,7) -- node[midway,left,rotate=90][yshift=.3cm]{Depth} (5,0);

\draw[->,line width=.3mm]  (8,7) -- (11,7);
\draw[->,line width=.3mm]  (8,7) -- (8,0);

\draw[<->] (6,7) -- node[midway,right]{$\sim \lambda_{R1}$} (6,6);
\draw[<->] (10,7) -- node[midway,right]{$\sim \lambda_{R2}$} (10,4);
\draw (5.75,6) -- (6.25,6);
\draw (9.75,4) -- (10.25,4);
\end{tikzpicture}

图表使用 中定义的曲线绘制controls，其余部分代码被重写以缩短。使用的是相对坐标：
