Frequency coding metasurface for multiple directions manipulation of terahertz energy radiation
AIP Advances, 2019 A multifunctional frequency coding metasurface is proposed in terahertz frequency band. Different from the previous coding metasurface with a fixed phase difference of the neighbor coding unit cells in the whole working frequency band, the proposed ...

Review of terahertz gradient metasurface
Dianzi Jishu Yingyong, 2019 Metasurface, a novel artificial electromagnetic material, its thickness is much smaller than the wavelength. By regulating the interaction between the sub-wavelength unit structure and the electromagnetic wave, the wave will undergo a phase or amplitude ...

A true metasurface antenna [PDF]
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016 AbstractWe present a true metasurface antenna based on electrically-small resonators. The resonators are placed on a flat surface and connected to one feed point using corporate feed. Unlike conventional array antennas where the distance between adjacent antennas is half wavelength to reduce mutual coupling between adjacent antennas, here the distance ...

Metasurface-based Mueller Matrix Microscope
, 2023 In conventional optical microscopes, image contrast of objects mainly results from the differences in light intensity and/or color. Muller matrix optical microscopes (MMMs), on the other hand, can provide significantly enhanced image contrast and rich ...

Organometallic Perovskite Metasurfaces [PDF]
Advanced Materials, 2017 Organometallic perovskites, solution-processable materials with outstanding optoelectronic properties and high index of refraction, provide a platform for all-dielectric metamaterials operating at visible frequencies. Perovskite metasurfaces with structural coloring tunable across visible frequencies are realized through subwavelength structuring ...

Metasurface-enabled compact, single-shot and complete Mueller matrix imaging
, 2023 When light scatters off an object its polarization, in general, changes - a transformation described by the object's Mueller matrix. Mueller matrix imaging polarimetry is an important technique in science and technology to image the spatially varying ...
