The purpose of the work is development of the kinetic theory of the ion-cyclotron waves in the dipole magnetospheric plasma and cylindrical mirror traps. The analysis is based on the theoretical analytical and numerical calculations. The self-consistent theory is developed to solve the linearized kinetic equations for perturbed distribution functions of the trapped particles in such 2D magnetized plasma systems as the Earth's magnetosphere and cylindrical mirror traps. There are obtained and analyzed the main contribution of the trapped particles with anisotropic temperature to the longitudinal and transverse dielectric tensor components for electromagnetic waves in the above mentioned plasma models. There are obtained the dispersion relations for cyclotron waves in the dipole magnetosphere and cylindrical open traps. The bi-maxwellian distribution function is considered as examples of the steady-state distributions of the energetic particles. There is studied the instability of the electromagnetic ion-cyclotron waves in the Earth's magnetosphere nearby the geostationary orbits. It is shown that the increment of this instability is much less than the corresponding expression for the 1D plasma models in the straight magnetic field.
