| Abstract: |
| Objective To study the design methods of elliptic cylindrical invisible cloak with non-singular electromagnetic tensors. Methods Based on the transformation optics theory, the coordinate expressions of space transformation were built, in order to deduce the electromagnetic tensors of the cloak. Then the non-singularities of the tensors were validated by Matlab software. Finally, simulation software based on finite element method was used to verify the electromagnetic invisible property of the cloak. Results The elliptic cylindrical cloak had good electromagnetic invisible property, and the electromagnetic tensors of the cloak were all non-singular. Conclusion Metamaterial electromagnetic invisible cloak with non-singular tensors could be theoretically realized by the space coordinate transformation designed. This non-singular method exploited the application of transformation optics theory in designing the metamaterial invisible devices. |
