Abstract :
Currents induced across a 20*5 dipole frequency selective surface have been computed using the iterative contrast source truncation technique. The results show the same non-uniform current distribution found earlier by the application of Pocklington´s equation, particularly at frequencies near the surface reflection band. Edge effects extend to the centre of a 40*5 array.
