We experimentally demonstrate, for the first time, an optically implemented blueshift tunable metamaterial in the terahertz (THz) regime. The design implies two potential resonance states, and the photoconductive semiconductor (silicon) settled in the critical region plays the role of intermediary for ...
\n\nThe design, characterization, and experimental demonstrations are presented for triple‐band, near‐perfect, composite metamaterials that absorb in the terahertz regime. Three absorption peaks are observed at 0.537 THz, 0.948THz, and 1.59THz with the respective absorption coefficients of 0.957, 0.9...
Terahertz metamaterials are designed to interact at terahertz (THz) frequencies, which is usually defined as 0.1–10 THz. Terahertz regime is located at the interface of electronics and photonics where technologies directly translated from microwave and optical regime generally fail to operate. This is...
Broadband planar and non-planar negative refractive index (NRI) metamaterial (MTM) designs consisting of a periodically arranged split ring resonator and wire structures are developed in the terahertz (THz) frequency regime using the Finite-Difference Time- Domain (FDTD) method. The novel MTM ...
Novel hybrid metal-graphene metamaterials featuring dynamically controllable single, double and multiple plasmon induced transparency (PIT) windows are numerically explored in the terahertz (THz) regime. The designed plasmonic metamaterials composed of a strip and a ring with graphene integration generate a...
Novel isotropic planar and three-dimensional negative refractive index (NRI) metamaterial (MTM) designs consisting of periodically arranged cross structures are developed in the terahertz (THz) frequency regime using group theory. The novel designs not only avoid magnetoelectric coupling but also enable ...
subwavelength scales, demonstrate infinite potential in extending the EAB of existing materials, particularly in the terahertz4, infrared5, and visible light spectra6. Nevertheless, achieving perfect absorption over an ultra–broad microwave frequency range, covering the entire 5 G communication band,...
Terahertz metamaterials comprise a periodic array of resonator elements disposed on a dielectric substrate or thin membrane, wherein the resonator elements have a structure that pro
