Abstract

An RF network solver has been developed in order to cross-validate the design of Ion Cyclotron Resonance Frequency array antennas. It has been used to evaluate their behavior under time-varying plasma scenarios and simulate there impedance matching algorithm and its feedback control. Typically a 1-second scenario with a 1 millisecond sampling requires around 10 seconds of computational time on a desktop computer. These tasks can be hardly handled by commercial RF software.
