The invention discloses a device for testing electromagnetic parameters of an artificial gaseous dust medium. The device is composed of a microwave loop and a gas dust loop. Wherein the microwave loop is composed of a vector network analyzer and a ventilated rectangular waveguide, and the gas dust loop is composed of a circulating power device and a ventilated rectangular waveguide; the circulating power device is composed of a fan and a PVC silicone tube; breather pipe connecting sleeves are arranged in two ports of the rectangular waveguide structure and used for being connected with a breather pipe and connected with a fan provided with a wind speed adjusting knob, the continuously-working fan enables the concentration of the gaseous electromagnetic absorption medium in the waveguide to be uniform, and PE transparent sealing films are added to the two ports, connected with the waveguide converter, of the rectangular waveguide respectively; observation is facilitated, and meanwhile the gaseous electromagnet
