Tailoring Metal and Insulator Contributions in Plasmonic Perfect Absorber Metasurfaces

“…[1][2][3][4][5][6][7] The photo-thermal generation of heat at the plasmon resonance is applied for photo-thermal therapy, is also used for thermal emitters, photothermal energy conversion, and photovoltaic applications. [8][9][10][11][12][13][14][15][16][17] Chiral optical metamaterials 18 introduce selectivity to enantiomers strongly required in bio-medical fingerprinting by SERS and SEIRA. With increasing demand of tailored plasmonic properties, various material are required including alloys, semiconductors, and graphene [19][20][21][22][23][24][25][26][27] with increasing versatility of engineered properties.…”

Kirchhoff's metasurfaces

“…Optical properties of the PPAs are zero transmission, T = 0, and close to zero reflection, R = 0, at the plasmon resonance. At the wavelength of plasmonic resonance, light should be absorbed by PPA [19,20,21,22,23,24,25,26,27,28,29]. For the ideal case, 100% of incident light can be absorbed at the resonance wavelength by PPA.…”
