CoREAS 是一种蒙特卡罗代码，用于模拟大面积空气簇射的无线电发射。它直接在 CORSIKA 中实现电磁辐射计算的端点形式。因此，它是无参数的，不对无线电信号的发射机制做出任何假设，并考虑到 CORSIKA 模拟的电子和正电子分布的完整复杂性。在本文中，我们通过在数十 MHz 至 GHz 频率的不同频率范围内进行仿真来说明 CoREAS 的功能，并特别描述了由于大气折射率变化而产生的切伦科夫效应导致的高频发射特性。
CoREAS is a Monte Carlo code for the simulation of radio emission from extensive air showers. It implements the endpoint formalism for the calculation of electromagnetic radiation directly in CORSIKA. As such, it is parameter-free, makes no assumptions on the emission mechanism for the radio signals, and takes into account the complete complexity of the electron and positron distributions as simulated by CORSIKA. In this article, we illustrate the capabilities of CoREAS with simulations carried out in different frequency ranges from tens of MHz up to GHz frequencies, and describe in particular the emission characteristics at high frequencies due to Cherenkov effects arising from the varying refractive index of the atmosphere.
