A quantitative study on the low frequency breakdown of EFIE

Zhi Guo Qian, Weng Cho Chew

Research output: Contribution to journalArticlepeer-review


A quantitative study is presented for the low frequency breakdown of the electric-field integral equation (EFIE) with the Rao-Wilton-Glisson basis function. The low frequency limit is ascertained hereby. Numerical experiments validate the conclusion. The line testing method is also compared with the Galerkin testing to dispel the misconception in the literature. The study thus provides a guideline for the application of EFIE in the full-field regime.
