Scattering database for spheroidal particles

Kurzfassung

We present a database containing light scattering quantities of randomly oriented dielectric spheroidal particles in the resonance region. The database has been generated by using a thoroughly tested T-matrix method implementation. The data possess a defined accuracy so that they can be used as benchmarks for electromagnetic and light scattering computations of spheroids. Within its parameter range the database may also be applied as a fast tool to investigate the scattering properties of nonspherical particles and to verify assumptions or statements concerning their scattering behaviour. A user interface has been developed to facilitate the data access. It also provides some additional functionalities like interpolations between data or the computation of size averaged scattering quantities. A detailed description of the database and the user interface is given followed by examples illustrating their capabilities and handling. On request, the database including the documentation are available, free of charge, on a CD-ROM (email to Jochen.Wauer@dlr.de or Karsten.Schmidt@dlr.de).
