The left part of the screen shows input data along with an illustration. Two cylindrical wires with diameter d and separated by a width, upper-case D are shown inside a cubical conductor. For the substrate, epsilon sub r equals 2.3 and sigma equals 0.0 S per m, while for the wires, sigma sub c equals 5.797E7 S per m. The following input parameters are specified in menu items:

Wire diameter, d equals 1.7794 millimeters

Centers distance, upper-case D equals 8.793 millimeters

Frequency, f equals 1.0E9 Hertz

The right part of the screen shows an output signal as a graph along with output data. The graph plotting Z sub 0 in ohms versus D in millimeters shows a curve that starts on the x-axis and moves in a steep upward slope, moving away from the y-axis and turning horizontal at the top. A point is marked on the curve where Z sub 0 value is 199.0 ohms.

The output data are as follows:
