Controlling Surface Waves on Finite Arrays of Active Elements With FSS Groundplane

7 CONTROLLING SURFACE WAVES ON FINITE ARRAYS OF ACTIVE ELEMENTS WITH FSS GROUNDPLANE 

In the previous section we found surface waves on the FSS groundplane most prevalent below 6.7 GHz. Let us now examine the more complicated problem
