Modeling an Impedance Tuner

2015
A model for precise identification of reflections in mixed distributed-lumped high frequency structures is proposed. The adequate structure that is suitable for this model class is a cascade of transmission lines tapped by lumped elements which are the source of the reflections.

Power combining port impedance model

1997 IEEE MTT-S International Microwave Symposium Digest, 2002
A novel way to characterize the port impedances of broadband combining networks has been developed. The impedance of a coupler port in the environment of a fully driven combiner is analyzed to develop a thorough understanding of the interaction of power MMICs and combiners in actual manufacturing environments.

Impedance Model Based Stability Control

2020
The instability of the drive system is caused by the interaction of the LC resonance and the constant power load (CPL), hence the active damping methods have been applied to damp the resonance and stabilize the drive system.

AC Impedance Modeling and Database

3rd International Energy Conversion Engineering Conference, 2005
A database of AC impedance measurements on lithium-ion cells is being developed at The Aerospace Corporation. Cells are being examined at various voltages and temperatures. Cell sizes range from 1.5 Ah to 100 Ah and encompass different geometries. Modeling is underway to enable comparison across differing cell lots, geometries, and sizes. Modeling also
