A method of substituting an electronic module with its Huygens box representation for the purpose of calculating the emitted field is discussed. It is pointed out that nearby obstacles may have harmful effect on the accuracy of such method. This is subsequently proven by performing finite-difference time-domain simulations on a simplified model of a printed circuit board (PCB) with a parallel open-ended cable in the vicinity. A solution to the problem is proposed: inclusion of the reduced model of the module inside the Huygens box, e.g. only the ground plane of the PCB. It is demonstrated that the described solution has the potential to decrease the errors to acceptable levels.
