In this paper, we review recent progress in terahertz metasurfaces mainly in the last 5 years. The first part covers nonuniform metasurfaces that perform beamforming in reflection and transmission. In addition,
Non-radiative optical modes attracted enormous attention in optics due to strong light confinement and giant Q-factor at its spectral position. The destructive interference of multipoles leads to zero net-radiation and strong field trapping. Such radiati

while the complex amplitude modulation is necessarily required to completely reconstruct full wave information of the wavefront of light in holography. However, methods based on metasurfaces can overcome this obstacle by utilizing various kinds of wavefront manipulating mechanisms...
or carbonitrides, known as “MXenes”, are a relatively new and large family of 2D materials. Since the discovery of the first MXene, Ti3C2in 2011 has become one of the fastest-expanding families of 2D materials with unique physiochemical features. MXene surface terminations with hydroxyl, ox...
in the visible range [61]. To increase the amplitude levels, CSRRs are chosen as the basic unit to achieve five-level amplitude and eight-level phase modulation at terahertz frequencies [62]. The phase and amplitude of the output orthogonally-polarized linear light can be simultaneously and ...

Metasurfaces refer to the sub-wavelength nanostructures that are capable of manipulating the amplitude, phase, polarization, and other characteristics of light, to enable diverse applications across the ultraviolet, visible, infrared, and terahertz spectra. In this review paper, we aim to provide an ...

By varying the lattice constant in the disk arrays, the coupling strength between the adjacent disks can be controlled, leading to a full tuning of the phase. The capability to modulate both phase and amplitude of light using metasurfaces has enabled ultrathin and high resolution computer-...
