Description
We present a simulation study of radio detection of Earth-skimming tau neutrinos produced by tau leptons
emerging from mountain ranges. Using CoREAS simulations of nearly horizontal extensive air showers, we
investigate the radio emission characteristics and effective detection areas across multiple frequency bands,
ranging from 30 - 80 MHz to the C-band at 3.4 - 4.2 GHz. Each frequency band implies distinct antenna designs
with different noise temperatures and beam patterns, and we study the optimal choice for maximizing detection
efficiency of tau neutrino-induced air showers. The signal amplitude profiles as a function of the distance and
viewing angle relative to Xmax are compared across bands, and trigger thresholds are derived from realistic
noise temperature estimates. The resulting neutrino flux sensitivities are compared for different bandwidth and
antenna choices, providing guidance for the design of future radio detector arrays targeting the PeV - EeV tau
neutrino flux.
