The device works as metamaterial because it shows the negative refractive index response at resonating frequency. Because of its large tunable range, the device can be used in several applications like optical communication, biosensors, and solar absorbers and can be integrated in photonic integrated ...
Here we review the recent development of metamaterial-based vacuum electronics for terahertz (THz) and microwave science and technology. The reversed Cherenkov radiation (RCR) in double-negative (DNG) metamaterials predicted by Veselago back in the 1960s has been experimentally verified in the ...
proposed a composite metamaterial terahertz modulator in 2015 based on GaN [16]. Compared with the second-generation semiconductor GaAs, GaN has a wide bandgap, electron mobility, and saturation speed. This work integrates an InAlN/AlN/GaN/AlN/GaN dual-channel heterostructure on an equivalent ...

This is a fundamentally different issue from the wavelength dependence of some other types of metasurfaces such as waveplates or absorbers that do not shape the beam. In addition, although related in some sense, this is physically different from the challenges faced in designing broadband (in ...
