1. A method of synthesizing an effective refractive index metamaterial, said method comprising the steps of:
a) analysing an effective index material by directing an electromagnetic plane-wave towards a surface of said metamaterial and calculating the polarization currents distribution field in said metamaterial, wherein said effective refractive index metamaterial is comprised of a plurality of layers of at least a first material having a first refractive index and at least a second material having a second refractive index;
b) filtering and sampling said polarization currents distribution field according to said layers, wherein said layers comprise pre-determined parameters requirements, said parameters including at least one of: refractive indexes of said first material and said second material, effective refractive index of said layer and thickness of said layer; and
c) determining a layer arrangement and thickness for said first and second materials comprising said plurality of layers, such that said polarization currents distribution field in said metamaterial imitates the current distribution field generated by surface currents corresponding to said sampled polarization currents distribution field.
