✦ Synopsis
The high-frequency skin-depth approximation for ohmic loss calculations is not ¨alid if the conductor thickness decreases and approaches the skin depth. This is the situation in many monolithic ( ) microwa¨e integrated circuits MMICs . The two asymptotes of loss, at dc and at high frequency of the abo¨e, are, in fact, known. This letter constructs a single synthetic asymptote that joins the two original asymptotes, and gi¨es good loss ¨alues at intermediate frequencies where the abo¨e skin depth occurs, not unlike a French cur¨e fitting.
