电磁系统的降阶建模被理解为系统的连续或离散模型通过实质上较低阶的模型的近似，但能够以足够的工程精度捕获原始模型的电磁行为。本文讨论了分布式电磁系统模型降阶的具体方法。结果表明，电磁模型降阶提高了计算效率，因此，有利于系统级建模和计算机仿真的多功能系统。所提出的方法是通过应用程序的降阶建模的高速互连，电磁波导，微带天线。
Reduced-order modeling of an electromagnetic system is understood as the approximation of a continuous or discrete model of the system by one of substantially lower order, yet capable of capturing the electromagnetic behavior of the original one with sufficient engineering accuracy. Specific methodologies for model order reduction of distributed electromagnetic systems are discussed in this paper. It is shown that electromagnetic model order reduction enhances computational efficiency and, thus, facilitates system-level modeling and computer simulation of multifunctional systems. The proposed methodologies are demonstrated through applications to the reduced-order modeling of high-speed interconnects, electromagnetic waveguides, and microstrip antennas.
