|Title:||Directional Cloaking by Quadruple Luneburg Lens System||Authors:||Evren, Aydın S.
graded photonic crystals
|Issue Date:||2018||Publisher:||IEEE||Source:||20th International Conference on Transparent Optical Networks (ICTON) -- JUL 01-05, 2018 -- Univ Politehnica Bucharest, Cent Lib, Bucharest, ROMANIA||Series/Report no.:||International Conference on Transparent Optical Networks-ICTON||Abstract:||In this study, we propose a method based on graded-index medium in order to cloak scatterer objects. We use discretized Luneburg lenses as a graded-index medium and the proposed structure consists of four discretized Luneburg lenses, i. e., it is can be considered as a quadruple Luneburg lens system. Numerical investigations for directional cloaking are performed by using finite-difference time-domain methods. It is shown that an object can be cloaked inside the dark zone of created by Luneburg lenses and the proposed structure can provide cloaking at optical wavelengths.||URI:||https://hdl.handle.net/20.500.11851/6540||ISBN:||978-1-5386-6605-0||ISSN:||2162-7339|
