“…With these versatile electromagnetic properties, metasurface has attracted enormous attention from the research communities. Based on strong wavefront modulation capability of metasurface within the sub-wavelength scale, many mete-devices have been demonstrated in the last ten years, such as meta-lens [16,21,94,155], invisible cloak [50,126], absorber [52,98,169], vortex beam generator [176], holography [43,113,193] and so on.…”

Metamaterials are composed of periodic subwavelength metallic/dielectric structures that resonantly couple to the electric and magnetic fields of the incident electromagnetic waves, exhibiting unprecedented properties which are most typical within the context of the electromagnetic domain. However, the practical application of metamaterials is found challenging due to the high losses, strong dispersion associated with the resonant responses, and the difficulty in the fabrication of nanoscale 3D structures. The optical metasurface is termed as 2D metamaterials that inherent all of the properties of metamaterials and also provide a solution to the limitation of the conventional metamaterials. Over the past few years, metasurfaces; have been employed for the design and fabrication of optical elements and systems with abilities that surpass the performance of conventional diffractive optical elements. Metasurfaces can be fabricated using standard lithography and nanoimprinting methods, which is easier campared to the fabrication of the counterpart 3 days metamaterials. In this review article, the progress of the research on metasurfaces is illustrated. Concepts of anomalous reflection and refraction, applications of metasurfaces with the Pancharatanm-Berry Phase, and Huygens metasurface are discussed. The development of soft metasurface opens up a new dimension of application zone in conformal or wearable photonics. The progress of soft metasurface has also been discussed in this review. Meta-devices that are being developed with the principle of the shaping of wavefronts are elucidated in this review. Furthermore, it has been established that properties of novel optical metasurface can be modulated by the change in mechanical, electrical, or optical stimuli which leads to the development of dynamic metasurface. Research thrusts over the area of tunable metasurface has been reviewed in this article. Over the recent year, it has been found that optical fibers and metasurface are coagulated for the development of optical devices with the advantages of both domains. The metasurface with lab-on fiber-based devices is being discussed in this review paper. Finally, research trends, challenges, and future scope of the work are summarized in the conclusion part of the article.‬‬‬‬‬‬‬

“…[18] The optical properties of such metasurfaces can be modulated across various wavelengths by carefully designing the meta-atoms. In recent years, a variety of optical devices, including metalenses, [19][20][21][22][23] structured light projection, [24][25][26] beam splitters and combiners, [27][28][29][30] meta-power-limiters, [31,32] carpet cloaking, [33,34] holograms, [35][36][37] and sensing [38][39][40][41] have been accomplished using both dielectric and plasmonic metasurfaces.…”

Metadevices are of paramount interest and importance due to their exotic capabilities in light control and manipulation in the nano‐scale regime. Various practical applications, including wearable devices, lasers, optical sensors, high‐resolution microscopy, both virtual and augmented reality, and metasails, require large‐scale metasurfaces. However, layout generation for large metasurfaces, faces challenges as up to billions of unit cells are required to create a metasurface, resulting in slow speeds and high memory demands. Here, a new framework namely ParallelGDS is proposed for fully parallel, ultra‐fast, and memory‐independent generation of graphic design system (GDSII) files for arbitrarily large metasurfaces. Compared to existing methods such as GDSTk, GDSPy, LUMERICAL's polystencil, the proposed framework significantly accelerates the layout generation process by factors of 10 to 100. More importantly, ParallelGDS drastically reduces the required memory (an problem) with an average reduction factor of where is the normalized metasurface diameter, as the framework uses only ≈2 GB of memory regardless of the size of the metasurface. The proposed framework offers complete control over memory requirements and parallelization levels of layout generation, ranging from single‐core CPU usage to multithreaded CPU utilization, and finally, full utilization of all GPU cores.

“…Metamaterials that are classified as artificial materials and have subwavelength-scale structures possess novel light manipulation properties that do not exist in nature, such as negative-index media [1,2], optical cloaking [3,4], and super-resolution images [5][6][7]. These materials have attracted considerable attention over the past two decades, and these impressive optical phenomena that metamaterials exhibit are connected to the localized surface plasmon resonances (LSPRs) [8] that arise from the collective oscillations of free electrons in subwavelength metallic meta-units.…”

Flat optics, metasurfaces, metalenses, and related materials promise novel on-demand light modulation within ultrathin layers at wavelength scale, enabling a plethora of next-generation optical devices, also known as metadevices. Metadevices designed with different materials have been proposed and demonstrated for different applications, and the mass production of metadevices is necessary for metadevices to enter the consumer electronics market. However, metadevice manufacturing processes are mainly based on electron beam lithography, which exhibits low productivity and high costs for mass production. Therefore, processes compatible with standard complementary metal–oxide–semiconductor manufacturing techniques that feature high productivity, such as i-line stepper and nanoimprint lithography, have received considerable attention. This paper provides a review of current metasurfaces and metadevices with a focus on materials and manufacturing processes. We also provide an analysis of the relationship between the aspect ratio and efficiency of different materials.
