Recent Advances of FEKO and WinProp

This paper describes recent advances of the commercial CEM code FEKO, as well as the wave propagation and radio network planning tool WinProp. This includes the simulation of characterized surfaces (complex radomes, frequency-selective surfaces) with RL-GO, a direct solver for ACA (adaptive cross approximation), and supporting FEM (finite element method) and MoM (method of moments) with SEP (surface equivalence principle) in the same model.
