| Abstract: |
| Lumped resistors are introduced to period structures to absorb the incident wave effectively，and this can reduce the RCS of target. Two absorbing structures, which are designed to be thin and light, are presented. The absorbing principle is analyzed and formulas of reflection coefficient are given. Samples of two absorbing material are fabricated and the absorbing performance is analyzed. |
