Evaluated @ Re(Rs)
@1MHz 1.4874E-3 Ohms/(sqrt(Hz)*meter)
@100MHz 1.0933E-3 Ohms/(sqrt(Hz)*meter)
@1GHz 1.2272E-3 Ohms/(sqrt(Hz)*meter)
@5GHz 1.3207E-3 Ohms/(sqrt(Hz)*meter)
The value at 1 MHz is curious in that it is larger than the
values at higher frequencies which seem to fall on a frequency
dependent monotonic line.
