Possible scenarios of auxiliary electron cyclotron plasma heating in various configurations of the next-generation open magnetic trap GDMT (Gas-Dynamic Multiple-mirror Trap) designed at the Budker Institute of Nuclear Physics are considered. For this purpose, a full-wave impedance approach is used to model the interaction of electromagnetic waves with hot plasma, which allows taking into account the interaction of electromagnetic and quasi-electrostatic modes in the vicinity of the electron cyclotron resonance in an axisymmetric magnetic configuration. Heating scenarios using the ordinary electromagnetic mode at the fundamental harmonic and extraordinary mode at the second harmonic are considered. For each case, the ranges of the setup parameters in which such a heating scheme can be effective are determined; optimal for the heating efficiency focusing parameters of the quasi-optical microwave beam are analyzed.
