Time-frequency representation (TFR) based on
Adaptive Optimal Kernel (AOK) normally performs well only
for monocomponent signals and has poor noise robustness. To
overcome the shortcomings of AOK TFR mentioned above, ...

A modified finite-difference time-domain (FDTD)
method is described in this paper. The absorption coefficient
which is frequency-dependent is considered, and it is used to
compute broadband acoustic scattering model of ...
