| Abstract: |
| A time domain singularity extraction technique is presented to calculate singular integrals in time domain electric field integral equation solver. In singularity extraction procedure, the time-retardation effects in time domain integrals are included. Numerical examples demonstrate that the presented method can greatly increase the accuracy of calculation of the self-interaction and near-interaction impedance matrix elements. |
