Abstract. Numerical model for electro-magnetic field in the compact range is developed. The model takes into account several factors that affect quasi-plane field in the quiet zone, factors produced by imperfection of radio-absorbing material in particular. A rigorous method for solving diffraction of the collimator’s field on RAM problem is presented. Results of computer simulations of the field in the compact range are presented.

Key words: 3D RCWA, radio-absorbing material, unechoic chamber, compact range.
