Description
Coupled resonant electrical circuits exhibit sensitivity to perturbation beyond linear. When the perturbation is the signal to be measured, operation of the circuitry near an exceptional point enhances the sensitivity by the nth root of the number of resonators. This presentation will describe exceptional points and their necessary conditions. Two examples will demonstrate exceptional point design simulations, one with gain and loss and the other with unidirectional coupling between the resonant tanks. In the first example, the input signal derives from a transformer, which could be the output of a PMT or a Rogowski coil. In the second, the input is a PMT signal.
