Description

Gravitational waves (GW) in the GHz band might be observed in the near future thanks to microwave cavities. In this work, we focus on GW sourced by hyperbolic encouters of black holes and take the GraHal experiment as a benchmark. We investigate in details the set of orbital conditions leading to a fixed emission frequency, analyze the typical time window of GW production and show how to maximize the signal. The associated maximum distance to the source is evaluated.
