A high-power density electric propulsion (EP) system is presented. High-power density functionality of the EP system is provided via thermal management structures that separately manage heat from a discharge chamber with electrically conductive inner/outer walls and an electromagnetic circuit of the EP system. The thermal management structures include separate radiators for rejection of heat from the discharge chamber and the electromagnetic circuit, the heat coupled to the radiators via respective thermal shunts. The thermal shunts include radially inwardly and/or outwardly projecting heat conducting structures that are thermally coupled to the discharge chamber and the electromagnetic circuit. Openings formed in annular structures of the electromagnetic circuit allow radial projection of the thermal shunts.
