We develop a high-order contrast source inversion method for solving the inverse scattering problem in electromagnetics. To decouple inversion from the mesh discretization, the algorithm supports high-order expansions for the fields, contrast and contrast sources on each element. The forward solver is a time-harmonic discontinuous Galerkin method formulated for Maxwell's curl equations and is sufficiently general to easily model a variety of imaging environments. Numerical and experimental results for transverse magnetic inversion are presented.
