设计了一种新型的介质激光波荡器。该设计的核心是一个周期性的介质结构，其两侧形成一个真空通道。通过引入两束特定波长的相向传播的平面激光波，在该真空通道内激励并产生一个相位同步的周期性电磁场。主要难点在于如何设计介质结构，使其在激光作用下，能够最大化提供偏转作用的横向电场Ey，同时必须将其他方向的场分量（如纵向场 Ez和加速场 Ex）对电子束的影响降至最低。 利用 COMSOL 求解了在两束相向传播的激光照射下，该周期性结构内部真空通道中的电磁场分布。通过仿真，验证即是否能成功在通道中心产生期望的周期性横向偏转电场，直观地展示电场沿不同方向的变化规律，从而评估波荡器的性能 ...

本文提出了一种新颖的介电激光加速器（DLA）结构，该结构利用三角梯度介电介质来增强逆切伦科夫效应（Inverse Cherenkov Effect, ICE），从而实现高梯度加速。逆切伦科夫效应是带电粒子从外部激光场中持续获取能量的过程，这在传统切伦科夫效应中是相反的，即粒子发射辐射。通过在介质中精确控制激光束的传播，可以产生一个与粒子速度同步的纵向电场分量，实现连续的净能量增益。为了验证这一概念并分析其性能，我们使用 COMSOL Multiphysics 进行了系统的仿真研究。仿真模型由一个位于自由空间域中的介电结构组成。我们应用散射边界条件（SBC ... Mehr lesen
