A hybrid method that combines the results of a commercial simulator with analytical
postprocessing is discussed and used to compute the dispersion diagrams of periodic …

Metamaterials are artificially engineered novel substances (or matter) that exhibit properties
not found in nature. One of the earliest examples of a metamaterial structure is the split-ring …

H01O 3/44(2006.01) H01O 3/22(2006.01) Surface scattering antennas provide adjustable
radiation H01O 13/28(2006.01) fields by adjustably coupling scattering elements along a …

Metamaterials are materials typically engineered with novel or artificial structures to produce
electromagnetic properties that are unusual or difficult to obtain in nature. Because of their …

This paper gives a basic review and a summary of recent developments for leaky-wave
antennas (LWAs). An LWA uses a guiding structure that supports wave propagation along …

Leaky waves have been among the most active areas of research in microwave engineering
over the second half of the 20th century. They have been shown to dominate the near-field …

Described embodiments include an antenna system and method. The antenna system
includes a Surface Scattering antenna that has an electromagnetic waveguide structure and …
