N2 - Active Plasma Resonance Spectroscopy (APRS) denotes a class of industry-compatible plasma diagnostic methods. One particular realizationof APRS with a high degree of geometric and electric symmetry is the Multipole Resonance Probe (MRP). The Ideal MRP is an even moresymmetric idealization which is suited for theoretical investigations. In this work, a spectral kinetic scheme is presented to investigate thebehavior of the Ideal MRP in the low pressure regime. Similar to the particle-in-cell method, the scheme consists of two modules, the particlepusher and the field solver. A Green’s function is defined to solve this potential problem. The spherical harmonics is employed to provide ageneral solution. With suitable truncation of the harmonics expansion, the complexity of the task can be reduced. The proposed kinetic modelovercomes limitation of the cold plasma model and covers kinetic effects. Numerical results illustrate the resonance behavior and dampingphenomena due to the escape of particles.
