The passive PT-symmetric model for SAW sensor. a The schematic diagram of the coupled resonators model and the real part of the eigenfrequency surfaces in the parameter space (ω1=ω2=ω0=0,γ0=0). The solid line denotes an EP line where γ=2κ. b A schematic diagram of the passive PT-symmetric SAW sensor. The coupled resonators are defined by three Bragg mirrors and coupled to the SAW transmission line. A sensitive layer is deposited onto the resonator I. External disturbance activates sensitive layer and introduce additional loss γ in the resonator I.
