Experimental Demonstration of Exceptional Points of Degeneracy in Linear Time Periodic Systems and Exceptional Sensitivity
A single time-periodic LC resonator is experimentally shown to host an exceptional point whose resonance frequency responds to small capacitance changes with a square-root scaling, demonstrating a new route to EPD-based sensing.
