Negative reflection and negative surface wave conversion from obliquely incident electromagnetic waves
Shuo Liu,Tie Jun Cui,Ahsan Noor,Zui Tao,Hao Chi Zhang,Guo Dong Bai,Yan Yang,Yan Yang,Xiao Yang Zhou +8 more
TL;DR: A simple coding method is proposed to allow dual functionalities (either PW or SW manipulations) under two orthogonal polarizations at arbitrarily oblique incidences, thus improving the adaptability of digital coding metasurfaces in more practical circumstances.
Dissimulation électromagnétique d'une membrure d'antenne par un réseau de lignes de transmission
TL;DR: In this project, a new way to design a strut by inserting a Transmission Line Network (TLN) is explored and it is suggested that TLNs have potential for cloaking an antenna strut.

Controlling Electromagnetic Fields
TL;DR: This work shows how electromagnetic fields can be redirected at will and proposes a design strategy that has relevance to exotic lens design and to the cloaking of objects from electromagnetic fields.

Metamaterial Electromagnetic Cloak at Microwave Frequencies

TL;DR: This work describes here the first practical realization of a cloak of invisibility, constructed with the use of artificially structured metamaterials, designed for operation over a band of microwave frequencies.
Journal ArticleDOI
Optical Conformal Mapping
TL;DR: A general recipe for the design of media that create perfect invisibility within the accuracy of geometrical optics is developed, which can be applied to escape detection by other electromagnetic waves or sound.

Achieving transparency with plasmonic and metamaterial coatings
TL;DR: Here it is seen how a proper design of these lossless metamaterial covers near their plasma resonance may induce a dramatic drop in the scattering cross section, making these objects nearly "invisible" or "transparent" to an outside observer--a phenomenon with obvious applications for low-observability and noninvasive probe design.

Tunneling of electromagnetic energy through subwavelength channels and bends using ε-near-zero materials
TL;DR: It is demonstrated theoretically that electromagnetic waves can be "squeezed" and tunneled through very narrow channels filled with epsilon-near-zero (ENZ) materials and it is discussed that in some cases the isotropy of the ENZ material may not be an issue.
