  The IceCube Neutrino Observatory has discovered a diffuse astrophysical flux
up to 10 PeV and is now planning a large extension with IceCube-Gen2, including
an optical array and a large radio array at shallow depth [1]. Neutrino
searches for energies >100 PeV are best done with such shallow radio detectors
like the Askaryan Radio Array (ARA) or similar (buried as deep as 200 meters
below the surface) as they are cheaper to deploy. This poster explores the
potential of opportunistically burying radio antennas within the planned
IceCube-Gen2 detector volume (between 1350 meters and 2600 meters below the
surface). A hybrid detection of events in optical and radio could substantially
improve the uncertainty of neutrino cascade direction as radio signals do not
scatter in ice. We show the first results of simulating neutrinos from an
astrophysical and a cosmogenic flux interacting with 9760 ARA-style vertically
polarized radio antennas distributed evenly across 122 strings.
