  4. Abstract:
  5. The need for antennas with improved characteristics for communication and radar applications has resulted in an ever-increasing demand for research in the field of high impedance surfaces, which can work as an artificial magnetic conductor. One method in fabrication of these surfaces is formation of a metamaterial by patterning a metallic surface in the shape of space filling curves (e.g. Hilbert or Peanu Curves). In this paper, we present a novel semi-analytical solution to the problem of plasmonic propagation on these surfaces. The method is based on a previously presented Green's function formalism, which has been reported in an earlier paper of ours. We have modified and improved the method for analysis of periodic structures with a large number of spatial harmonics, and used different methods to get the necessary stabilization. Here propagating modes of different structures and their corresponding frequencies are calculated, and the possibility of frequency gap formation and stability of the method are investigated
