A comparison of infrared extinction performances of bioaerosols and traditional smoke materials
TL;DR: In this article, the complex refractive indices of traditional smoke materials and bio-aerosols in the 2.5-15 μm wavebands were calculated and the IR transmittances of different smoke materials in the smoke box experiment were measured to calculate their mass extinction coefficients.

Aggregation-driven reductions in the mass extinction coefficient of bioaerosols
TL;DR: In this paper, the authors used the cluster-cluster aggregation model to establish the structures of aggregated particles at different stages in the aggregation of bioaerosols and calculated the extinction parameters of the aggregated particle by using the discrete dipole approximation method.

Analysis of optical properties of bio-smoke materials in the 0.25-14 μm band
TL;DR: In this article, the spectral reflectance of three eukaryotic bio-smoke materials and three prokaryotic BioSmoke materials in the waveband from 0.25 μm to 14 μm was measured based on the Kramers-Kroning algorithm.
Complex Refraction Indices of Expanded Graphite Deduced from Its Reflection Spectra in Infrared Band
TL;DR: In this paper, the complex refractive index of expanded graphite (EG) pellet in the 0.24~2.6 μm and 2.5~25 μm waveband was calculated by Kramers-Kronig(K-K) relation and Bruggeman effective medium theory.

Effects of relative humidity on the broadband extinction performance of bioaerosol.
TL;DR: The simulation results and experimental data from an aerosol chamber experiment show that as the relative humidity values above 70%, the broadband extinction performance of bioaerosol will be increased with humidity, and the variation law of broadband extinction performances in different humidity conditions was obtained by simulation.

TL;DR: In this article, a thorough study on the relation between the plasma emission and the change of the silicon nitride thin films refractive index was presented, where thin films were grown by reactive magnetron direct current sputtering technique and deposited onto silicon wafers at different fluxes of Ar and N2 and at different working pressures.

Measurement and analysis on complex refraction indices of pear pollen in infrared band
TL;DR: The results indicate that 18 degrees angle of incidence and different reflectivities at high and low frequencies have little effect on the results, and it is practicable to calculate the complex refractive index of pollen based on its reflection spectral data.

Complex refractive index of nonspherical particles in the visible near infrared region: application to Bacillus subtilis spores.
TL;DR: A method for the estimation of optical constants in the ultraviolet-visible-near-infrared (UV-Vis-NIR) region of nonspherical particles in a suspension at concentrations where multiple scattering is significant finds that the optical constants obtained using the RGD approximation matches those obtaining using the T-matrix method to within experimental error.
