A numerical study of a thin-wire probe inside a slotted rectangular cavity is presented in this work. The results obtained with the 3-D full-wave method of moments based code FEKO is compared to the computations in [1]. The motivation for this study stems from the wide usage of high power RF excitations in electronic systems. Electromagnetic coupling and interference [2] in electronic devices (computers, sensors, control and communication devices, etc.) is of increasing concern due to the presence of both intentional and un-intentional internal/ external electromagnetic sources. After the preliminary comparison of results we introduce a finite conductivity into the walls of the cavity to resemble more practical problems for simulations with FEKO.
