我想用表示随距离衰减的波的曲线替换“Power-Up Link”和“Backscattered Link”标签的水平箭头，就像我手绘的曲线一样。Power-up Link 中的波的振幅应该大于 Backscattered Link 中的波的振幅。我不知道如何做到这一点，而且我还没有找到任何类似的图。
此外，我想问如何设置“场景设置”框盖的确切宽度，从阅读器容器的左侧到标签容器的右侧。我一直在测试值，minimum width=但\node[brwblock,shift={(0,8.0cm)},minimum width=18cm,font=\fontsize{12}{0}\selectfont] at ($(Reader)!.5!(TAG)$) {\textbf{Scenario Setup}};它不适合两个容器的宽度。
text width=能量采集器盒也有同样的问题。我想将此盒从 FSA 的顶部扩展到无源收发器的底部，但使用这种样式很难匹配这个长度vertblock。
类似地，我已经将yshift能量收集器框和其余框之间的箭头线的值调整为水平，但很难确定匹配的 y 移位是多少，以使水平箭头从该框指向 FSA 和 PHY 层以及无源收发器框。
我不知道这些问题是否可以在一个问题中回答，或者我应该分别询问。

您可以只使用expanding waves装饰物并剪掉不需要的部分。

如果我将上部弹夹瞄准镜替换为
\begin{scope}
\clip[postaction=draw] ([yshift=24pt]AT.east) --([yshift=14pt]PTtag.west)--([yshift=10pt]PTtag.west) --([yshift=0pt]AT.east);

([yshift=12pt]AT.center) --([yshift=6pt]PTtag.west);
\end{scope}
我明白了
因此波浪在到达点（即右侧框）处更宽。解释您的评论的第二种方法是使进入的上部波浪在到达点处比下部波浪在离开点处更宽。例如，可以通过以下方法实现
\begin{scope}
\clip ([yshift=24pt]AT.east) --([yshift=15pt]PTtag.west)--([yshift=9pt]PTtag.west) --([yshift=0pt]AT.east);
\draw[red,thick,decorate,decoration={expanding waves,angle=20}]
([yshift=12pt]AT.center) --([yshift=6pt]PTtag.center);
\end{scope}
\begin{scope}
\clip ([yshift=-12pt]PTtag.west) --([yshift=-9pt]AT.east) --([yshift=-7pt]AT.east)
-- ([yshift=-4pt]PTtag.west);
\draw[red,thick,decorate,decoration={expanding waves,angle=20}]
([yshift=-8pt]PTtag.center) --([yshift=-8pt]AT.east);
\end{scope}
