摘要: The complex permittivity of liquids is measured with a microwave cavity. measurements are conducted for the TE111, TE112, TM010, and TM011 modes in circular cylindrical loss tangent dirty oil (after 6000 mi) found to be three times higher than one clean oil. relative dielectric constant not noticeably effected. ©1999 John Wiley & Sons, Inc.
