摘要
本文提出了一种近似方案，该方案将近似解与误差估计器相结合，以加速基于 RWG 的矩方法（MoM）与电场积分方程（EFIE）的自适应 h 精化。该方案通过使用近场矩阵求解近似解来有效实现。研究了与该方案相结合的几种传统误差估计器。与使用完整的 MoM 系统相比，它在保持细化效果的同时显著降低了计算成本。数值结果表明，该方案可以加速自适应细化，显著减少计算时间和内存需求。
An efficient adaptive h-refinement for the RWG-based electric field integral equation applied to antennas with waveport
An approximation scheme that combines approximate solutions with error estimators to accelerate the adaptive h-refinement of the RWG-based method of moments (MoM) with the electric field integral equation (EFIE) is presented. The scheme is effectively implemented by using the near-field matrix to solve the approximate solution. Several conventional error estimators incorporated with the scheme are investigated. Compared to using the full MoM system, it significantly reduces the computational cost while maintaining the refinement effect. Numerical results indicate that the scheme could accelerate the adaptive refinement, yielding significant reductions in computational time and memory requirements.
