Abstract
We show the recently discovered ghost waves - a special class of non-uniform electromagnetic waves in biaxial anisotropic media - can be used for optical sensing based on exceptional points. In addition to showing high sensitivity and precision, the proposed sensor employs simple planar geometry and is robust against noise.
