Non-Hermitan degeneracies, also known as exceptional points (EPs) have been the center of much interest
due to its unique branch point topology and defective eigenspace. However, despite much interesting
phenomena with EPs, not much work has been done yet in a controllable manner. Here, we demonstrate
electrical access to the EP in only single non-Hermitian metasurface via asymmetric control of loss in
the comprising SRR modes. Electrostatically tuned graphene is utilized to provide a perturbation to the
SRR modes resulting in changes in the dissipation rate. By mapping out the eigentransmission surface
as a function of frequency and graphene Fermi energy, a branch point singularity corresponding to the
EP is observed. Furthermore, the coalescence of eigenstates at the EP is veried by plotting the transmission
eigenstates on a Poincare sphere. Our results provide various applications such as asymmetric
transmission and EP-locked sensor for terahertz conductive materials.
