Abstract :
The finite-difference time-domain (FDTD) method was used to calculate infrared extinction by aerosol particles of brass 70 Cu/30 Zn. The number of aerosol particles used in the calculations was in the range of 10/sup 4/ to 2.56/spl times/10/sup 5/. The refractive index of aerosol particles was taken to be n/sup */=16.87+j51.59. The cell sizes of these cubic particles were varied from 0.02 to 0.5 /spl mu/m to examine the extinction characteristic. Results on the extinction cross section are compared with experimental data in the infrared (/spl lambda/=10 /spl mu/m) region.<>
