论文摘要
通过直立的等离子体平板，考虑到具有磁场的垂直等离子间的Epstein曲线，考虑到直立的等离子体平板，考虑了通过站立线性香肠快速磁性波从燃烧环的调节强度的调节。发射是陀螺仪（GS）性质的，是由中等相对论的电子引起的，这些电子在振荡的平板中占据一层，即发射和振荡的体积不重合。结果表明，微波对线性香肠波的响应高度非线性。发现非线性的程度定义为第二次谐波的傅立叶功率与主谐波的傅立叶功率的比率，这取决于GS源宽度和视角的宽度组合，并且在光学厚度和光学薄的微米谱系中的光学厚度不同。这种效果可以被视为诊断加速电子填充区域的横向尺度的潜在工具。
The modulation of the microwave emission intensity from a flaring loop by a standing linear sausage fast magnetoacoustic wave is considered in terms of a straight plasma slab with the perpendicular Epstein profile of the plasma density, penetrated by a magnetic field. The emission is of the gyrosynchrotron (GS) nature, and is caused by mildly relativistic electrons which occupy a layer in the oscillating slab, i.e., the emitting and oscillating volumes do not coincide. It is shown that the microwave response to the linear sausage wave is highly non-linear. The degree of the non-linearity, defined as a ratio of the Fourier power of the second harmonic to the Fourier power of the principal harmonic, is found to depend on the combination of the width of the GS source and the viewing angle, and is different in the optically thick and optically thin parts of the microwave spectrum. This effect could be considered as a potential tool for diagnostics of the transverse scales of the regions filled in by the accelerated electrons.
