Rare Metals, Volume 42, Issue 1, Page 234-243, January 2023., 2023 Graphical abstract Abstract The heating and helicity effects induced by circularly polarized laser excitation are entangled in the helicity‐dependent all‐optical switching (HD‐AOS), which hinders understanding the magnetization dynamics involved. Here, applying a dual‐pump laser excitation, first with a linearly polarized (LP) laser pulse followed by a

Study & Realization of EMC for the Multimedia Mobile Handset [PDF]
, 2005 高速电子器件工作时会产生很强的电磁干扰，这不仅可能使产品无法通过有关的电磁兼容性标准测试，甚至可能连其自身的稳定性也无法保证。特别是手机，电磁兼容一直是手机硬件设计的一个难点，并且不是依靠理论完全能够解决的，只能从实践设计中总结经验。在手机产品研发过程中，由于产品可靠性不高、工作不稳定而浪费大量的时间进行调试，甚至失去市场时机而造成重大损失的事例时有发生。所以手机的电磁兼容性预测和设计非常重要，在原理设计和PCB设计阶段就应该引起足够的重视。本文首先从理论上阐述手机电磁兼容问题 ...
