Abstract
In this paper we reveal the first time-reversal-invariant topological metamaterial exhibiting robust photonic surface states protected against disorder on all length scales. By combining chirality and hyperbolicity we show that polarization eigenstates with opposite handedness can become well separated in k-space leading to a new form of topological order.
