Recently, a cloaking technology using reflecting elements has been marked. Cloaking devices using reflectarray have simple and very thin structure, so they are especially suitable for cloaking. This paper proposes a carpet cloaking using wideband reflectarray.
This paper proposes a primary radiator using leaky-wave antenna with left-handed cylindrical waveguide. Negative permeability is realized by the cutoff TM01 mode in a hollow waveguide and also negative permittivity is realized by the cutoff dominant TE mode in a sector waveguide with a ridge. Then the left-handed leaky-wave antenna with slits opened is applied to a primary radiator without sub-reflecting...
This paper proposes an approach to design the carpet cloak by using reflecting elements. Using such a technique, it is possible to realize invisibility by thinner cloaks. Furthermore, an illusion cloaking using the metasurface is investigated numerically and experimentally.
This paper has proposed a method constructing composite right/left-handed cylindrical waveguides. In this waveguide, negative permeability is realized by the cut-off TM01 mode in a hollow waveguide and also negative permittivity is realized by the cutoff dominant TE mode in a sector waveguide with a ridge. Usefulness of the proposed cylindrical waveguide is verified from the calculated values for...
