Abstract
We consider a medium exhibiting non-reciprocal magneto-electric effect known as Tellegen response captured by the equations of axion electrodynamics. Here, we investigate the implications of the complex-valued Tellegen response, discuss the conditions for its emergence and possible material realizations outlining a route to its experimental identification from the Stokes parameters of the reflected light.
