“…Fano resonance is the typical case of narrowband application. The sharp resonance peak complemented by strong local field enhancement is amongst the most important aspects of Fano resonance [ 32 , 33 ]. It is the foundation of several practical applications such as nonlinear photonics and biological sensing.…”

Throughout human history, the control of light, electricity and heat has evolved to become the cornerstone of various innovations and developments in electrical and electromagnetic technologies. Wireless communications, laser and computer technologies have all been achieved by altering the way light and other energy forms act naturally and how to manage them in a controlled manner. At the nanoscale, to control light and heat, matured nanostructure fabrication techniques have been developed in the last two decades, and a wide range of groundbreaking processes have been achieved. Photonic crystals, nanolithography, plasmonics phenomena and nanoparticle manipulation are the main areas where these techniques have been applied successfully and led to an emergent material sciences branch known as metamaterials. Metamaterials and functional material development strategies are focused on the structures of the matter itself, which has led to unconventional and unique electromagnetic properties through the manipulation of light—and in a more general picture the electromagnetic waves—in widespread manner. Metamaterial’s nanostructures have precise shape, geometry, size, direction and arrangement. Such configurations are impacting the electromagnetic light waves to generate novel properties that are difficult or even impossible to obtain with natural materials. This review discusses these metamaterials and metasurfaces from the perspectives of materials, mechanisms and advanced metadevices in depth, with the aim to serve as a solid reference for future works in this exciting and rapidly emerging topic.

“…To obtain this goal, the inner side of the back surface of the cell needs to be textured properly to make longer wavelengths scatter and diffract back into the active absorption layer, as shown in Figure 8 d. A plasmonic nanostructure can be applied in the thin-film solar cell to harvest the maximum amount of trapped light [ 163 , 164 , 165 ]. This plasmonic nanostructure can be designed to absorb different wavelengths of light, such as those in the infrared [ 166 , 167 , 168 ] and visible range [ 169 ].…”

Enhancement of the electromagnetic properties of metallic nanostructures constitute an extensive research field related to plasmonics. The latter term is derived from plasmons, which are quanta corresponding to longitudinal waves that are propagating in matter by the collective motion of electrons. Plasmonics are increasingly finding wide application in sensing, microscopy, optical communications, biophotonics, and light trapping enhancement for solar energy conversion. Although the plasmonics field has relatively a short history of development, it has led to substantial advancement in enhancing the absorption of the solar spectrum and charge carrier separation efficiency. Recently, huge developments have been made in understanding the basic parameters and mechanisms governing the application of plasmonics, including the effects of nanoparticles’ size, arrangement, and geometry and how all these factors impact the dielectric field in the surrounding medium of the plasmons. This review article emphasizes recent developments, fundamentals, and fabrication techniques for plasmonic nanostructures while investigating their thermal effects and detailing light-trapping enhancement mechanisms. The mismatch effect of the front and back light grating for optimum light trapping is also discussed. Different arrangements of plasmonic nanostructures in photovoltaics for efficiency enhancement, plasmonics’ limitations, and modeling performance are also deeply explored.

“…In plasmonic nanostructures, plasmon-induced transparency (PIT) profile was reported by Zhang et al (Zhang et al 2008) and great interest was attracted (Wu et al 2012;Dyer et al 2013;Zhao et al 2016). In metamaterials and plasmonic nanostructures, the PIT originates from the interference of resonant modes (Zhang et al 2008;Muhammad and Khan 2015;Muhammad and Khan 2016) analogous to the atomic quantum system in which an electric dipole couples to quadrupole state (Muhammad and Khan 2015;Muhammad and Khan 2016). The dispersive nature of PIT is auspicious for the propagation of slow light (Yannopapas et al 2009), narrow lineshape for biosensing (Dong et al 2010;Liu et al 2009), and lasing (Deng and Dong 2013).…”

We investigate plasmon-induced anti-transparency (PIAT) modes with a metallic metasurface on a dielectric substrate through the finite-element method. Multiple spectral splits are achieved by breaking the symmetry of square-ring resonators. The asymmetry of the structure is attained by incorporating cuts in the rings and increasing displacement of cuts in opposite directions. The high asymmetry decreases the spectral width and enhances the intensity of PIAT resonances. A unified mechanism for generating the PIAT resonances and plasmon-induced transparency (PIT) resonances is studied and agrees with the simulation results. These resonances are highly sensitive to the type of background materials and can be used for detecting cancerous and healthy tissues. A high figure-of-merit (FoM) of 808 is calculated for biosensing. The multiple high-quality factor resonances can also be used for optical filters (band-stop filtering for PIAT modes and band-pass filtering for PIT modes), slow light devices, and switching.
