论文摘要
Marchenko聚焦功能在其本质波场上，可以满足波浪方程，但要受一组边界，初始和聚焦条件的影响。在这里，我们展示了如何通过找到对波场重建反转问题的解决方案来建模的Marchenko聚焦功能。我们的解决方案产生了聚焦函数的所有元素，包括逃生，折射和被困的波（隧道）。我们的示例表明，由于强烈的逃生波的出现，通过数值手段计算的较高维度的聚焦函数解决方案具有挑战性。
Marchenko focusing functions are in their essence wavefields that satisfy the wave equation subject to a set of boundary, initial, and focusing conditions. Here, we show how Marchenko focusing functions can be modeled by finding the solution to a wavefield reconstruction inversion problem. Our solution yields all elements of the focusing function including evanescent, refracted, and trapped waves (tunneling). Our examples indicate that focusing function solutions in higher dimensions are however challenging to compute by numerical means due to the appearance of strong evanescent waves.
