Backscattering From Randomly Placed Dirichlet Particles
收藏资源简介:
<strong>Summary:</strong> A simulated data set of backscattered waves, governed by the 2D wave equation, from randomly placed Dirichlet particles. The particles are circular with 0.2 < radius < 2.0 and 1% < volume fraction < 20%. The incident wave is of the form e<sup>i k (x - x<sub>R</sub> - t)</sup> where the particles are placed in the halfspace x>0 and the backscattering is emitted and received at (x<sub>R</sub>, 0) with x<sub>R</sub> = -10.0. The data named bunny and bunnytest is for incident waves with 0 < k < 1 (where the term e<sup>- i k t</sup> factors out). The data named train and test is for incident waves of the form e<sup>0.1</sup><sup>(x - xR - t)^2</sup>, with 9.5 < t < 98. <strong>Format:</strong> An example of how to use the data is given in [4]. To load the data requires the packages [1] and [2] in the language Julia v0.5> [3]. When using load(filename) the data will automatically be loaded as an array of type FrequencySimulation or of type TimeSimulation.
