The characteristic impedance of large-scale rectangular strip transmission line facilities used for such purposes as EMI susceptibtity testing, biological exposures, etc., is discussed. These Iines are characterized by a thin center conductor and an air dielectric. Impedance data obtained by earlier workers, using different analytical and numerical techniques, are reviewed and compared. Exact data are available for the problem involving a center conductor of zero thickness while for the center conductor of finite thickness data are available which are accurate to less than 1.25 percent.
