Validation of straight-line signal propagation for radio signal of very
inclined cosmic ray air showers
An ongoing challenge for radio-based detectors of high-energy cosmic particles is the accurate description of radio signal propagation in natural non-uniform media. For radio signals originating from extensive air showers, the current state of the art simulations often implicitly assume straight-line signal propagation. This while the refraction due to a …
