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.

Visible and infrared optical properties of stacked cone graphite microtubes
TL;DR: Differences in the absorptive and scattering optical properties of heat-treated, vapor-grown, graphite microtubes consisting of nanotubes in a "stacked cone" configuration are most distinct for visible and near infrared wavelengths; in this wavelength region, the imaginary index falls progressively to less than half that for the computed mixture.

Determination of infrared complex refractive index of microbial materials

Differential multiply subtractive Kramers-Kronig relations
TL;DR: In this paper, the authors apply the multiply subtractive Kramers-Kronig (MSKK) method to the derivative of a medium's optical transfer function and obtain a method that integrates two different techniques, MSKK and spectral ballistic imaging, without the need to measure the phases at all but rather its derivative.
