1. An artificial magnetic conductor (AMC), the AMC characterized by an effective media model comprising:

  • a first layer and a second layer, each layer having a layer tensor permittivity and a layer tensor permeability, each said layer tensor permittivity and each said layer tensor permeability having non-zero elements on a main diagonal only, x and y tensor directions being in-plane with each respective layer and z tensor direction being normal to each layer the first layer including a specific arrangement of conducting and dielectric regions chosen to produce, resonance at predetermined multiple frequencies which are not necessarily harmonically related.
