The use of genetic algorithms to maximize the performance of a partially lined screened room [PDF]
, 2002 This paper shows that it is possible to use genetic algorithms to optimize the layout of ferrite tile absorber in a partially lined screened enclosure to produce a "best" performance.

Enhanced transmission performance based on ultrathin broadband circular hole array metasurface
Materials Research Express, 2021 A high transmittance broadband metasurface with Si and STO layers is verified in 100–130 THz. This metasurface achieves a transmission peak (Amplitude 78.1%, Resonance frequency 112.2 THz) with a complete Si layer, or a broad transmission band (Average ...

Physical absorption of CO2 and propene into toluene/water emulsions [PDF]
, 1994 The physical absorption of CO2 and propene into toluene/water emulsions is studied in a stirred cell and laminar film absorber. Experimentally observed masstransfer rates are compared to an absorption model, based on Higbie's penetration theory ...

Coronal lines and the warm X-ray absorber in Seyfert 1 Galaxies [PDF]
, 2000 The connection between the coronal lines and the warm absorber is examined systematically. In an earlier work it was found that the coronal line emitting plasma and the warm absorber gas share the same density and temperature.

Plasmonic parametric absorbers
Optics Letters, 2018 Exploiting the dynamics of Plasmonic Parametric Resonance (PPR), we introduce the theory of Plasmonic Parametric Absorbers (PPA). The key insight informing the PPA idea is that in the PPR process a pump field experiences an extinction rate that strongly depends on the intensity of the pump itself, creating two distinct regimes: one of weak absorption ...

Coherent Asymmetric Absorbers [PDF]
Physical Review Applied, 2021 Most applications of metasurfaces require excitation and control of both electric and magnetic surface currents. For such purpose, the metasurface must have a finite thickness to handle magnetic surface currents. For metasurface sheets of negligible thickness that offer only electric response, coherent illumination can compensate the need to create ...

Discovery of a Dwarf Post-Starburst Galaxy Near a High Column Density Ly-alpha Absorber [PDF]
, 2003 We report the discovery of a dwarf (M_B = -13.9) post-starburst galaxy coincident in recession velocity (within uncertainties) with the highest column density absorber (N_HI = 10^15.85 cm^{-2} at cz = 1586 km/s) in the 3C~273 sightline. This galaxy is by
