The insulation surrounding the RG cable carries a low impedance of around 50 or 52 ohms. It generally serves for generating signal connections that are of low power. The RG cable is   impedance varies from that of the intrinsic impedance in free-space ( Ω) for 1 cell, to a value tending to zero for bulky segmentations. Once the characteristic impedance is defined, a 2-D FDTD electromagnetic simulation can be carried out by following the procedures presented in [2]. First, an open-circuit termination is roughly defined as   CABLE DESIGNERS GUIDE HOW TO SPECIFY CABLE Insulated Conductors Specify quantity, gauge, stranding and insulation type for the conduc-tors.

  We define the C/C impedance Z 0 of the line as the ratio of positively traveling voltage wave to current wave at any point on the line. Z 0 is analogous to η (intrinsic impedance of the medium of wave propagation). By substituting eqs, (8) and (9) into eqs.

And we must keep in mind that there is a real and an imaginary component to impedance. So we’re actually talking about a 50 Ohm real + 0 Ohm imaginary (or 50 Ohm magnitude, 0 degrees phase) test port impedance. And except for a few fortunate instances, most DUTs don’t come with a standard coaxial
