Thermally excited phonon spectra of two-dimensional Yukawa solids and liquids in the presence of an external magnetic field are studied using computer simulations. Special attention is paid to the variation of wave spectra in terms of several key parameters, such as the strength of coupling, the screening parameter, and the intensity of the magnetic field. In addition, comparisons are made with several analytical theories, including random-phase approximation, quasilocalized charge approximation, and harmonic approximation, and the validity of those theories is discussed in the present context.
