Physical wavelets and their sources: Real physics in complex spacetime
摘要：
第一次，完整的源分布的发射和吸收的声波和电磁波的定义和计算，在时空和傅立叶空间。最令人惊讶的是，与从原始小波得到的相当复杂的时空表达式相比，傅立叶源非常简单。这表明，相关的脉冲束传播可能在发射和吸收过程中发挥重要作用，包括聚焦或“方向性”。“它还开辟了构建基于FFT的算法，用于声学和电磁波的脉冲束分析的道路。
英文摘要：
For the first time, complete source distributions for the emission and absorption of acoustic and electromagnetic wavelets are defined and computed, both in spacetime and Fourier space. The biggest surprise is the great simplicity of the Fourier sources as compared to the rather convoluted spacetime expressions obtained from the original wavelets. This suggests that the associated pulsed-beam propagators may play a fundamental role in emission and absorption processes including focus or "directivity." It also opens the way to constructing FFT-based algorithms for pulsed-beam analyses of acoustic and electromagnetic waves.
