“…Another problem of PBTM arises when beams intersect more than one surface. If an intersecting polygon is detected, there are two solutions: The original beam is followed by its central axis ray 4,20,22 or the original beam can be split. 24,25 Beam-splitting algorithms possibly make simulations more accurate, but they are computationally voracious.…”

“…For grazing incidence or relatively small sized panels, another reflection modeling could be used. 22,23 For absorption coefficient boundary conditions, the angle dependence and phase shift on reflection are neglected. Therefore a real-valued and positive reflection coefficient is calculated as…”

“…In this study, the beam tracing method [23][24][25] is employed to simulate the sound propagation in a reverberation chamber. Triangular beams, which are emitted from a source, are followed by their central axes ͑hereafter rays͒ without splitting algorithm.…”

“…They concluded that the early response at mid-frequencies is more accurate if the phase changes due to propagation are included instead of using pure energies. 134 This corresponds to the phase restoration technique described in Sec. III A.…”
