T-matrix method (Tmat) - (for example, Mischenko et al 2004c, 1994a, Barber and Hill 1990) is a method of calculating light scattering properties. This method, introduced by Waterman (1971, 1965), is also known as the null-field method and extended boundary conditions method (EBCM). It relies on expanding the incident, transmitted, and scattered fields into spherical vector wave functions, and linearly relating the incident field to the scattered field via the T-matrix (transition matrix). In principle the method can be applied to a particle of any shape in arbitrary orientation. The T-matrix characterizes inherent properties of a particle (shape, structure) but not its orientation or details of the electromagnetic wave field incident on the particle (for example, Kahnert et al 2001b, p. 3110). Mischenko (1991) and Khlebtsov (1992) developed means for analytic averaging of the particle orientation effects in the T-matrix approach which reduce considerably the computation time involved in calculating light scattering by randomly oriented particle ensambles. The SVM (separation of variables method) is equivalent to the T-matrix method (Schmidt et al 1998). [AJB, © Crown Copyright 2007]

Porstendorfer J et al 1999 compared this method with the Asano and Yamamoto method (AYM) for gold nanospheroids. [MJ]
