摘要(Abstract)：

为解决固体物理课程中能带理论抽象、理论与实践脱节的教学痛点，本文构建“基于非厄米趋肤效应的电压信号放大器设计”作为项目式（Project-Based Learning,PBL）教学案例。该项目紧扣矢量声学传感器的宽频测量需求，以能带理论为基础，拓展非厄米体系拓扑特性，利用非厄米趋肤效应的体态局域化机制，通过调控电容参数使非布洛赫相位因子满足|β|>1，实现电压沿电路节点的指数级放大。教学中，学生全程参与可行性分析、仿真计算、样件加工及测试，深化了对能带理论与非厄米物理的理解，锻炼了跨学科实践能力与科研实践能力。该案例为固体物理“理论—项目—应用”的教学转化提供了可行路径。
