Eisvogel

Eisvogel is a tool to calculate the time-domain antenna signal in a radio neutrino experiment. It uses an electrodynamic Green's function to efficiently propagate radiation through complex environments.

Key features

• All electrodynamic effects are included: no ray-tracing or geometric optics are assumed
• Supports arbitrary linear, inhomogeneous, anisotropic materials
• Interfaces to CORSIKA 8 to simulate signals from microscopic showers

Eisvogel is still under development. If you want to help, or just learn more about the project, feel free to contact us.

Installation

mkdir build && cd build
cmake -DBUILD_TESTS=ON -DBUILD_EXAMPLES=ON ..
make -j5

To also build the components for the calculation of the Green's function do (this requires MEEP to be installed and available)

cmake -DBUILD_MEEP=ON ..

If you want to build the C++ unit tests, add

cmake -DBUILD_TESTS=ON ..

Support for Corsika 8

Eisvogel can interface with Corsika 8. To enable, build Eisvogel as follows

cmake -DBUILD_CORSIKA=ON -DCMAKE_INSTALL_PREFIX=/path/to/eisvogel-install ..
make -j5
make install
