在本文中，我们提出了使用ETD方法模拟电磁波在二阶极点洛伦兹介质中传播的更新方程的公式。如稍后将示出的，与ADE方法相比，该公式将导致更少的存储器存储要求。数值结果也表明，ETD方法比ADE方法和PLRC方法具有更高的精度。
In this paper, we present the formulation of update equations for modeling electromagnetic wave propagation in second-order pole Lorentz media using the ETD method. As will be shown later, the formulation will result in less memory storage requirement compared to the ADE method. Numerical results also indicate that the ETD method is more accurate compared with other methods such as the ADE method and PLRC method.
