Mechanical 144GHz beam steering with all-metallic epsilon-near-zero lens antenna
(AIP Publishing, 2014) Artículo / Artikulua,
An all-metallic steerable beam antenna composed of an ε-near-zero (ENZ) metamaterial lens is experimentally demonstrated at 144 GHz (λ0 = 2.083 mm). The ENZ lens is realized by an array of narrow hollow rectangular waveguides ...
Lensing system and Fourier transformation using epsilon-near-zero metamaterials
(American Physical Society, 2012) info:eu-repo/semantics/article,
Metamaterials and metastructures with effective relative permittivity near zero exhibit unusual wave properties such as uniform phase distributions across such domains. Here we discuss the possibility of using ε-near-zero ...
Terahertz epsilon-near-zero graded-index lens
(Optical Society of America, 2013) info:eu-repo/semantics/article,
An epsilon-near-zero graded-index converging lens with planar faces is proposed and analyzed. Each perfectly-electric conducting (PEC) waveguide comprising the lens operates slightly above its cut-off frequency and has ...
