Davor Zaluški, in collaboration with Prof. Silvio Hrabar and Damir Muha, developed fully functional artificial DB surface. The performed experiments clearly showed that this surface behaves as a PEC for one polarization of impinging EM wave, while for other polarization it has the PMC properties. To the best of our knowledge, this is the first experimental realization of a fully functional DB surface and it is reported in June issue of Applied Physics Letters (http://dx.doi.org/10.1063/1.4883405).
