DOI: 10.1021/acsomega.9b02506
Abstract: Two types of plasmonic metamaterial absorbers (PMAs) formed from patterned all-dielectric resonators are designed and demonstrated experimentally in the terahertz (THz) range. Both PMAs use a simple grating design on highly N-doped silicon. The first… read more here.

DOI: 10.1021/acsphotonics.8b00676
Abstract: In this work, we show that modulating the fractal dimension of nanoporous gold allows its effective dielectric response to be tailored over a wide spectral range of infrared wavelengths. In particular, the plasma edge and… read more here.

DOI: 10.1103/physrevb.95.045149
Abstract: Nonlocal effects, requiring wave-vector- $(q$-) dependent dielectric response functions, are becoming increasingly important in studies of plasmonic and metamaterial structures. The phenomenological hydrodynamic approximation is the simplest and most often used model but with limited… read more here.

DOI: 10.3390/nano13101650
Abstract: In this study, we demonstrate the localized surface plasmon resonance (LSPR) in the visible range by using nanostructures on mirrors. The nanohemisphere-on-mirror (NHoM) structure is based on random nanoparticles that were obtained by heat-treating silver… read more here.
