| Abstract: |
| The effect of cell rotating on electromagnetic scattering is analyzed by employing the method of moments(MoM) based on triangular base function.Using coordinate transform,the MoM formula is obtained after rotation.Then the effect of rotating on the electromagnetic scattering characteristics is analysed.Compared with traditional frequency selective surface(FSS),the novel frequency selective structure has the advantages of easy implementation and tuning. |
