| Abstract/Summary |
The T-matrix method is widely used for the calculation of scattering by particles of sizes on the order of the illuminating wavelength. Although the extended boundary condition method (EBCM) is the most commonly used technique for calculating the T-matrix, a variety of methods can be used. Because the T-matrix depends only on the properties of the scatterer and the wavelength and not on other properties of the incident field, the T-matrix method is especially well-suited to repeated calculations involving varying illumination. Thus, it can be highly desirable to express the scattering properties of a given arbitrary particle as a T-matrix. However, the standard EBCM is only applicable to homogeneous scatterers, necessitating the use of other, more general methods. We consider some general principles of "hybrid" T-matrix methods - calculating T-matrices using other techniques for calculating scattering - and consider some specific methods. In particular, we discuss the application of time-domain methods which offer the possibility of simultaneous multiple-wavelength or multiple-size calculations.
