Emulation of lossy channels using a low loss microstrip trace with added lossy materials

Long traces or cables usually show a smooth rolloff with increasing frequency leading to Inter-Symbol Interference Jitter. The paper proposes a method for emulating such channel link performance by using a short microstrip trace with added lossy material. The paper focuses on the characterization and selection of lossy materials for emulating long channels using a short low loss trace with added lossy material.
