NuRadioMC是用于模拟超高能中微子探测器的框架，这类探测器测量中微子引发的粒子级联产生的无线电信号，被应用于不同的无线电中微子实验。我们提出了针对多层指数折射率模型的解析光线追踪方法的扩展，其中完整的折射率剖面由一组不同的单指数层描述，支持各实验站点的真实介质描述，同时保持计算效率。该方法还能对大气进行真实的指数折射率描述，使我们可以对折射率非平滑变化上的信号传播进行建模。本报告概述了多层解析光线追踪方法的基础，并展示了一些应用示例。
英文摘要
NuRadioMC is a framework for the simulation of ultra-high-energy neutrino detectors that measure the radio signal emitted in neutrino-induced particle cascades used in different radio neutrino experiments. We present an extension to the analytic raytracing method for multilayered exponential refractive index models, where the full refractive index profile is described by a set of different single-exponential layers, supporting realistic medium descriptions at various experiment sites while maintaining computational efficiency. This approach also enables a realistic exponential refractive index description of the atmosphere and allows us to model signal propagation over non-smooth changes in the refractive index. This report outlines the fundamentals of the multilayered analytic raytracing method and shows some applied examples.
