Summary:
A method to estimate the current distribution on multi-layer printed circuit board (PCB) by measuring the near-field distribution is proposed. Microstrip transmission line on the PCB is divided into segments which are small compared with the wavelength. An electric field integral equation (EFIE) is established to relate the near-field to the current on these segments. The current is estimated by measuring the nearfield, evaluating the mutual impedance between the current segments, and solving the EFIE. Experimental results are presented and compared with the numerical results confirming the validity of the proposed method.
