Abstract
With the increasing demands for new biological extinction materials in military and civilian fields, the artificially prepared flocculent biological particles are equivalent to bullet rosette particles. Then the unit particles with different numbers and lengths of branches are built, and the aggregated particles with different structures are built further. Next the structures of biological particles are characterized by parameterization. And the discrete dipole approximation method is used to calculate the extinction efficiency factor for biological particles. The results indicate that the structures and spatial arrangement of unit particles have great impact on the extinction performance of biological particles. The extinction performance of unit particles is positively correlated to the number and length of branches in the far infrared waveband. Furthermore, the extinction performance of aggregated particles is positively correlated to the porosity in the far infrared waveband. The model provides a theoretical basis for the further development and morphology control of biological extinction materials.
