Abstract

We develop a general formalism to study the reflection of radio waves, generated by ultra high energy cosmic ray events, from the Antarctic ice surface. Our formalism is based on plane wave decomposition of spherical waves and is applicable to the observations made by the ANITA detector. We find that our numerical result shows good agreement with the calibration data obtained by the High-Altitude Calibration (HiCal) experiment. ce features such as the local sastrugi. We incorporate these roughness models to investigate whether the non-uniform surface roughness of Antarctica can explain these anomalous events.

球形电磁波从不平坦的南极表面反射的一般处理及其对ANITA探测到的神秘事件的影响

摘要

我们发展了一种一般形式主义来研究由南极冰面反射的超高能宇宙射线事件产生的无线电波。我们的形式主义基于球面波的平面波分解,并且适用于ANITA检测器进行的观测。我们发现我们的数值结果与通过高空标定(HiCal)实验获得的标定数据显示出良好的一致性。ce功能,例如当地的sastrugi。我们并入了这些粗糙度模型,以研究南极洲不均匀的表面粗糙度是否可以解释这些异常事件。
