Latest Patents

Kazemi Varnamkhasti holds a patent titled "Exceptional points of degeneracy in linear time periodic systems and exceptional sensitivity." This patent discloses an exceptional points of degeneracy (EPD) system that utilizes a resonator with a linear time-periodic variation. Unlike prior art systems that require two coupled resonators with precise values of gain and loss, his system simplifies the process by only needing the tuning of the modulation frequency or modulation depth. This innovation allows for easier implementation in electronic systems. The EPD represents a point in a system parameters' space where two or more eigenstates coalesce, leading to unique properties not found at other non-degenerate operating points. The patent also includes experimental data demonstrating the existence of a second-order EPD in a time-varying single resonator, showcasing the expected sensitivity of its resonances to circuit perturbations. The system exhibits both structural degenerate and non-degenerate resonances, significantly enhancing its sensitivity performance to minor perturbations. This unique sensitivity can be harnessed to create exceptionally sensitive sensors based on a resonator through the application of time modulation.
