Common-mode currents in cables connected to electronic devices play a crucial role in radiated emissions. This paper focuses on estimating the radiated emissions of the cable connected to an electronic device based on the measurement of the common-mode current near the cable attachment point. From the single measurement, the distribution of the common-mode current is calculated using the method of moments and the distribution is used in turn to calculate the radiated emissions at arbitrary points in space. The proposed method’s performance is experimentally verified using a battery-fed 10 MHz oscillator-based circuit attached to a 1.5 m open-ended two-wire transmission line within the frequency range of 30 to 300 MHz. The experimental results demonstrate that the proposed method aligns well with directly measured radiated fields in a standard EMC anechoic chamber.
