Scattering by Aggregated Fibres Using a Multiple Scattering T‐Matrix Approach

In this paper we consider electromagnetic wave scattering by aggregated fibres using a multiple scattering approach. Scattering by particles of complex shape such as concave particles, torus, or clusters of fibres can not normally be computed using the T‐matrix method. In this paper we are proposing a decompositioning approach to handle this scattering problem. A scattering particle is decomposed into a number of basic units and scattering by such an ensemble of basic constituents is computed using a multiple scattering T‐matrix approach. The range of validity of this approach is investigated by providing exemplary computation results for single fibres and aggregated fibres.
