This paper proposes a closed-form empirical equation to account for the eddy-current loss due to metal fill. For a given average magnetic field the formula estimates the loss due to in-plane fills. The formula was developed over a wide range of dimensions and frequencies up to 50 GHz, and was found to be accurate to within 8% over this range. We also verify the formula using an example microstrip.
