摘要

本文提出了一种有效的时域数值方法来模拟德鲁德临界点(DCP)介质的宽带响应。该方法在前人研究和发展的不连续伽辽金时域(DGTD)方法的基础上，采用并置E-J格式对电场和极化电流进行离散。同时提出了一种龙格-库塔法和纽马克法的杂交方法来求解相关的一阶和二阶时间辅助微分方程。通过与商业软件的对比，验证了该方法的有效性和高效性。

An efficient wideband numerical simulation technique for nanostructures comprised of DCP media

This work presents an efficient time domain numerical approach to simulate the wideband response of Drude-critical point (DCP) media. Based on previous research and development of the Discontinuous Galerkin Time Domain (DGTD) method, this approach applies the collocated E-J scheme to discretize the electric fields and polarization currents. A hybridization of the Runge-Kutta and Newmark methods is also proposed to solve the associated first-order and second-order temporal auxiliary differential equations. The effectiveness and efficiency of this new approach is validated through comparison with commercial software.
