TOPICA  is presently the only code which combines accurate 3D modelling of ICRF antennas with a realistic 1D plasma model. The natural outputs of TOPICA are the currents on the conductors and the admittance matrix of the antenna. Although these parameters are sufficient to evaluate new antenna designs and to design matching circuits for them, the need to also investigate their vulnerability to sheath effects necessitates the explicit calculation of the radiated fields. A post-processing module has been developed which calculates these fields, both in the vacuum gap between the antenna aperture and the plasma edge, and in the plasma itself.
