Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...

Gaoya dianqi, 2013 理论分析了定向耦合器监测端脉冲信号波形与辐照等效源波形的关系,实验研究了在定向耦合器输入功率不变的前提下,直通端阻抗的变化对耦合端监测功率的影响,证明了理论分析的正确性,仿真分析了对称定向耦合器耦合端和直通端的相位差对监测波形的影响。结果表明:对于非线性互联系统,在保证系统响应相同的条件下,注入电压与辐照场强的关系是线性的;在系统端口匹配的情况下,监测电压与辐照等效源电压为线性关系;耦合端和直通端的相位差会导致监测波形畸变,应选用反对称或非对称定向耦合器作为监测设备。
