Acoustic focusing by the spectral division method

I have extended the spectral division method (SDM) in a recent paper presented at the ISCCSP 2010 for the reproduction of focused sources. The mathematical analysis revealed some quite interesting facts about the role of evanescent contributions in this context. … Continue reading

Comparison of focusing by time-reversal techniques and WFS

Time-reversal acoustic focusing and focused sources reproduced by Wave Field Synthesis (WFS) are closely related in the underlying physical concepts. However, the goal of time-reversal techniques is typically to concentrate acoustic energy at the focus point, whereas WFS aims at … Continue reading
