  • Gravitational wave propagation beyond geometric optics.- [PDF] - [Article]

    Giulia Cusin, Macarena Lagos
     

    It is standard practice to study the lensing of gravitational waves (GW) using the geometric optics regime. However, in many astrophysical configurations this regime breaks down as the wavelength becomes comparable to the Schwarzschild radius of the lens. We revisit the lensing of GW including corrections beyond geometric optics. We propose a perturbative method for calculating these corrections simply solving first order decoupled differential equations. We study the behaviour of a single ray and find that the polarization plane defined in geometric optics is smeared due to diffraction effects, which leads to the rise of apparent vector and scalar polarization modes. We also study the impact of diffraction on the pseudo-stress energy momentum tensor of the gravitational field.
