Impedance Matching
Application ID: 54371
This tutorial drives a capacitively coupled plasma with an L-type matching network at high and low powers. At low power, where the harmonics in the current are low, prefect matching is obtained at the chosen power value. Sweeps over power, frequency, and pressure are performed and their effect on the match power transfer ratio and efficiency are examined. Finally, a sweep is performed over a higher power range. The presence of sizable harmonics in the current causes an impedance mismatch.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
