Sphere of arbitrarily polarized exceptional points with a single planar metasurface

Abstract Exceptional points (EPs) are spectral singularities of non-Hermitian systems and represent the coalescence of eigenvalues and eigenstates. Traditional photonic systems typically exhibit coalesced eigenstates that correspond to circular polarizations of a specific handedness, thereby restric...
