摘要：

A general wavelet packet tree is proposed to generate a pre-defined wavelet packet basis for the efficient representation of electrodynamic integral equations. The wavelet packet decomposition tree is constructed by zooming in along the spectral oscillation frequency of the free-space Green's function. This is in contrast to the conventional wavelet transform which zooms in along the lowest spectral frequency. Numerical results show the transformed moment matrix based on the pre-defined wavelet packet basis has about O(N-1.3) above-threshold elements for typical scatterers.
