Abstract
Plasmonic Dipole Resonators In article number 2312170, Xuanru Zhang, Tie Jun Cui, and co-workers propose an exceptional point (EP) state in a microwave plasmonic dipole resonator. The geometric asymmetry leads to strong asymmetry of the non-Hermitian Hamiltonian, resulting in enhanced frequency splitting signals. It combines the EP's high sensitivity and strong plasmonic wavelength compression. The minimum detectable metal scatterer features a diameter of λ0/280, and the reporting limit for glucose reaches 0.26 µmol.
