​Dr. Wu's recent paper "A semi-Dirac point and an electromagnetic topological transition in a dielectric photonic crystal" got accepted by Optics Express today. In this paper, she studied the classical semi-Dirac point and revealed the relation between a semi-Dirac point and an electromagnetic topological transition.  This is the first observation of semi-Dirac point in classical systems. She investigated the linear-parabolic disperion relations and the effective medium of the system.  She also demonstrated the drastic change in the wave manipulation behavior across the semi-Dirac point.
