Abstract: A multi-layered thin combiner (MLTC) is provided herein. The MLTC may include: a plurality of connectable layers each having a separate active area coated with a primary partially reflective filter; wherein each active area comprises a discrete fraction of an effective aperture; and wherein the active areas are configured to align, when said connectable layers are connected, to collectively define a complete effective aperture.

Abstract: A method of synthesizing an effective refractive index metamaterial, the method may include the steps of: a) analysing an effective index material by directing an electromagnetic plane-wave towards a surface of the metamaterial and calculating the polarization currents distribution field in the metamaterial, wherein the 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 the polarization currents distribution field according to the layers, wherein the layers comprise pre-determined parameters requirements, the parameters including at least one of: refractive indexes of the first material and the second material, effective refractive index of the layer and thickness of the layer; and c) determining a layer arrangement and thickness for the first and second materials comprising the plurality of layers.
