Planoconcave lens by negative refraction of stacked subwavelength hole arrays
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
This work presents the design of a planoconcave parabolic
negative index metamaterial lens operating at millimeter wavelengths
fabricated by using stacked subwavelength hole arrays. A staircase
approximation to the ideal ...
Negative refraction in a prism made of stacked subwavelength hole arrays
(Optical Society of America, 2008)
info:eu-repo/semantics/article,
Metamaterial structures are artificial materials that show
unconventional electromagnetic properties such as negative refraction
index, perfect lenses, and invisibility. However, losses are one of the big
challenges to be ...
