## Abstract In this paper, an efficient time domain formulation is proposed for a lowβfrequency scattering by a complicated inhomogeneous dielectric scatterer. The formulation is based on the Born approximation and a sampling theorem. To extend the valid region of the proposed solution, the Rayleig

Asymptotic and exact local radiation boundary conditions (RBC) for the scalar time-dependent wave equation, ΓΏrst derived by Hagstrom and Hariharan, are reformulated as an auxiliary Cauchy problem for each radial harmonic on a spherical boundary. The reformulation is based on the hierarchy of local b
