Exceptional Points of Degeneracy (EPD) in Circuit Configurations

Brief Description

This technology enhances the sensitivity of sensors through exceptional points of degeneracy in various circuit configurations.

Full Description

The invention focuses on making sensitive oscillators using the instability in circuits with exceptional points of degeneracy (EPD) in distinct circuit configurations, including gyrator-based coupled resonators, PT-symmetry coupled resonators, and single resonators with time-varying components. It highlights the circuits' high sensitivity to minute changes in resistance, capacitance, and inductance, leading to an enhanced sensitivity of the oscillation frequency to perturbations of the reading element of a sensor ( capacitor, an inductor, or a resistor). The research explores the conditions for stability and instability within these configurations, turning instabilities into advantages for creating highly sensitive oscillators.
