METAMATERIAL WAVEGUIDE LENS

摘要

A metamaterial waveguide structure is disclosed. In some approaches the metamaterial waveguide structure is compressed along an optical axis using transformation optics techniques. An example is a Rotman lens that is compressed by 27 percent along the optical axis while maintaining the beam steering range, gain and side lobe amplitudes over a broad frequency range. In some approaches the metamaterial waveguide structure includes a plurality of complementary metamaterial elements patterned on a conducting surface of the waveguide.

1. An apparatus, comprising:
a parallel plate waveguide having an input port region, an output port region, and a plurality of subwavelength apertures within one or more conducting surfaces of the parallel plate waveguide, the plurality of subwavelength apertures providing a respective plurality of individual electromagnetic responses; where the plurality of individual electromagnetic responses provides a substantially increased optical distance between the input port region and the output port region.
