Check out Eric’s Latest publication, Synthesis of High Speed Channels from Shorter Elements


In my latest article in the May 2017 issue of IEEE Electromagnetic Compatibility Magazine, my former student, Karthik Radhakrishna, and I describe a simple process using an open source tool to concatenate S-parameter elements.

S-parameters are often called a behavioral model for interconnects. They describe everything there is to know about the electrical properties of an interconnect. A complex channel is often constructed of many individual components. When simulating a channel. we get models for each of these elements from different sources, 2D field solvers, 3D field solver, measurements, or even vendors.

How do we build a single, composite S-parameter model from all these different  models? S-parameters, by themselves, do not cascade together.

This articles explains the details of how to build a single composite S-parameter model, and how to evaluate if you have it correct.  You can access a copy from here.
