A computational scheme is proposed to generate a T matrix for an arbitrarily-shaped homogeneous particle. The method models the internal field within the particle as a directional spectrum of plane waves. A system of equations for the plane-wave coefficients is obtained by application of the model to a discrete-dipole representation of the particle.
