20.500.12556/RUL-168024 Experimental determination of effective light transport properties in fully anisotropic media Structurally anisotropic materials are ubiquitous in several application fields, yet their accurate optical characterization remains challenging due to the lack of general models linking their scattering coefficients to the macroscopic transport observables and the need to combine multiple measurements to retrieve their direction-dependent values. Here, we present an improved method for the experimental determination of light-transport tensor coefficients from the diffusive rates measured along all three directions, based on transient transmittance measurements and a generalized Monte Carlo model. We apply our method to the characterization of light-transport properties in two common anisotropic materials—polytetrafluoroethylene tape and paper—highlighting the magnitude of systematic deviations that are typically incurred when neglecting anisotropy. scattering anisotropy material properties simulations light scattering transmittance diffusion picosecond phenomena signal intensity refractive index sipanje anizotropija lastnosti materialov simulacije sipanje svetlobe transmitanca difuzija pikosekundni pojavi lomni količnik true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-25 14:46:16 2025-03-25 14:46:19 2025-03-26 03:58:23 0000-00-00 00:00:00 2024 0 0 Str. 056017-1-056017-8 no. 5, art. 056017 Vol. 4 Sep./Oct. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 535.36 2791-1519 10.1117/1.APN.3.5.056017 229763587 056017_1_(2).pdf 056017_1_(2).pdf 1 188580AD2F07ED72BD1DAB00BA1CB9D8 d2a15064304512f20fd9d087226d6dcf3ac6ef4044089214563f561fe05b426f e2310f97-097e-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201004 https://www.spiedigitallibrary.org/journals/advanced-photonics-nexus/volume-3/issue-05/056017/Experimental-determination-of-effective-light-transport-properties-in-fully-anisotropic/10.1117/1.APN.3.5.056017.full 1 91868f14-097e-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201003 Fakulteta za elektrotehniko 0 0 0
