To address this, FEKO includes a complete integrated cable modeling tool that permits the analysis of the radiation (and irradiation) of cables. There can be noisy signals propagating through different cables in the car and the radiation from such cables is coupled into different antennas, adding noise, thus reducing the performance of systems like analog or digital radio. For example, coupling of radiated fields from cable harnesses to windscreen antennas (and to other types of antennas) in a vehicle, also related to CISPR-25 EMC standard (CISPR is the International Special Committee on Radio Interference or Comité International Spécial des Perturbations Radioélectriques) that sets industry test standards. There are multiple key use cases related to EMI being solved with FEKO.
In addition to this, model decomposition in FEKO works with equivalent antenna and EMC sources to reduce computational requirements. One way to easily calculate antenna coupling in FEKO is through S-parameters, where users can see the effect of changing antenna loads without re-running the solver, easily visualize results for a large number of ports and plot a co-site interference matrix to visually identify and analyze critical couplings. Depending on the problem and its electrical size and complexity, users just need to select one of the solvers in FEKO. and the HIRF SE Consortium, HIRF-SE FP7 EU project).
