Electromagnetic wave propagation in static black hole spacetimes: an effective refractive index description in Schwarzschild geometry

Abdullah Guvendi, Omar Mustafa Semra Gurtas Dogan, Hassan Hassanabadi

We investigate electromagnetic wave propagation in static, spherically symmetric black hole spacetimes using a covariant and gauge-invariant framework based on the established Maxw…
