• ### Design of multi-band frequency selective surfaces using multi-periodicity combined elements

Publication Year: 2009, Page(s):675 - 680
| | PDF (1860 KB)

Traditional multi-band frequency selective surface (FSS) approaches are hard to achieve a perfect resonance response in a wide band due to the limit of the onset grating lobe frequency determined by the array. To solve this problem, an approach of combining elements in different period to build a hybrid array is presented. The results of series of numerical simulation show that multi-periodicity c...
