RF-inductor modeling for the 21st century By Leslie Green, Gould-Nicolet Technologies
The familiar three-element model of an inductor has some serious shortcomings, even at frequencies well below the inductor's self-resonant frequency. A more useful model correctly predicts an inductor's behavior over a range of frequencies.
