A coupled dielectric-metal metasurface (CDMM) consisting of amorphous silicon (a-$\textit{Si}$) rings and subwavelength holes in $\textit{Au}$ layer separated by a $\textit{SiO}_{2}$ layer is presented. The design parameters of the CDMM is numericall

A Superoscillatory lens (SOL) is known to produce a sub-diffraction hotspot which is useful for high-resolution imaging. However, high-energy rings called sidelobes coexist with the central hotspot. Additionally, SOLs have not yet been directly used

Plasmonic quasicrystals with 5-fold rotation symmetry are shown to offer broadband transmission enhancement. The observed linear transmission enhancement leads to broadband second harmonic generation in a wide incident angle range contrary to unpatte

Plasmonic metasurface based superabsorbers exhibit high absorbance. While the absorption peak can be tuned by the geometry/size of the sub-wavelength resonator, broadband absorption can be obtained by harnessing spectrally shifted resonances of multi

Plasmonic quasicrystals with designable spectral response have been demonstrated with large transmission enhancement. We show that the corresponding plasmon mediated local field is strong enough to generate second harmonic over broadband.

Surfaces patterned with arrays of quasi-periodic air holes having conical depth profile have been studied for their effectiveness in suppressing air-substrate reflection in the wavelength range of 450-1350 nm (limited by our measurement). The role of

This paper will extend the existing absolute quality-of-service (QoS) scheme to a service-differentiated Optical Burst-Switched Network. We will show that the burst loss probability of our service-differentiated model will decrease compared to the pr
