Transmission line(TL) model was applied to cutoff probe(CP), which is a microwave resonance probe for measuring electron density. Application of preceding model(circuit model) for analysis of characteristics of CP was limited

to low electron density regime(< 1010 cm-3). In order to supplement the circuit model we introduced TL model and compared results between TL model and three-dimensional full-wave electromagnetic(3-D FWEM) simulation. Simulation

results of TL model are in good agreement with that of the a 3-D FWEM simulation in both low and high electron density regime. Furthermore the results of TL model are the same with that of circuit model in the low electron density

regime. Therefore by using TL model we can expand the applicable range of cutoff probe up to high electron density regime.
