transmission line calculator - line pair

illustrate: input frequency, center distance and wire diameter. if you want to specify a conductor other than copper, select custom and specify the conductivity of the conductor material. if you want to specify a dielectric other than air, select one of the other optional materials or select custom and specify the relative permittivity of the dielectric. click the "calculate" button to display the calculated transmission line parameters. if the center spacing is in centimeters or millimeters, the length per unit parameter is "per meter". if center-to-center spacing units are in inches or mils, they are "per foot."

notice: all materials are non-magnetic (i.e. μ = μ0). dielectric losses are not modeled.
