Basically, Rybak's study involved creating a PCB test vehicle as described by the S3 method, measuring the S-parameters
of 50 [ohm] striplines within the various dielectric materials of the test vehicle, establishing a mathematical model to simulate the result of conductor and dielectric losses over frequency, then changing the values of the model parameters for dielectric and conductor loss until the simulation fit the results for insertion loss for the striplines stemming from the S-parameter
data files for the UBSC 935 151 423 510 (0201, 10nF, 11V), UBSC 935 151 424 610 (0402, 100nF, 11V) and UBSC 935 151 723 510 (0201, 10nF, 30V) are now available for download from the Modelithics website.
For multiple power/GND plane pairs, generate separate S-parameter
models for each.
profile at higher implantation energies will be the average S-parameter
of the annihilation in each of the two phases in the polymer.
At this energy a drastically decrease in the S-parameter
comparable with a drastically increase in the W-parameter.
provided a measure of the concentration of defects or voids in the coating, which could be measured as a function of distance from the outer surface.
The ASL 3000RF incorporates advanced capabilities, including Credence's patented MVNA technology, a new method for measuring S-parameters
, or scattering parameters, with greater accuracy.
The resulting impedance variation effects are included during time domain simulation and s-parameter
Codeveloped with industry vendors, the HyperLynx Alliance virtual labs include the complete HyperLynx design environment, partner IBIS-AMI or S-parameter
electrical models, a reference design-based test case, and a step-by-step instruction guide.

In the simulation, the interconnect was characterized using a combination of 2-D and 3-D field solvers, as well as S-parameter
models for the connectors between boards.
The SPARQ signal integrity network analyzer makes S-parameter
measurements quickly and is a fraction of the price of a Vector Network Analyzer (VNA).
