In this paper an electromagnetic characterization of an EMI/EMC test facility for electric propulsion thrusters is presented. The facility consists of a dielectric vacuum chamber placed in a semi-anechoic room and connected to a Large Vacuum Test Facility. To this end, an analysis of the electromagnetic field radiated outside a canonical infinite dielectric cylinder by an internal line source has been conducted. First the two-dimensional Green's Function for the electromagnetic radiation by a line source inside the canonical dielectric hollow cylinder is developed. Then, two high frequency emission models based on Geometrical Optics and on an iterative implementation of the Physical Optics are formulated and the results compared to those of the Green's function method. The numerical results show very good agreement between the simplified high frequency techniques and the exact formulation.

Abstract

In this paper an electromagnetic characterization of an EMI/EMC test facility for electric propulsion thrusters is presented. The facility consists of a dielectric vacuum chamber placed in a semi-anechoic room and connected to a Large Vacuum Test Facility. To this end, an analysis of the electromagnetic field radiated outside a canonical infinite dielectric cylinder by an internal line source has been conducted. First the two-dimensional Green's Function for the electromagnetic radiation by a line source inside the canonical dielectric hollow cylinder is developed. Then, two high frequency emission models based on Geometrical Optics and on an iterative implementation of the Physical Optics are formulated and the results compared to those of the Green's function method. The numerical results show very good agreement between the simplified high frequency techniques and the exact formulation.
