Analog Realization of Fractional-Order Capacitor and Inductor via the Caputo–Fabrizio Derivative

Journal of Advanced Computational Intelligence and Intelligent Informatics, 2021
Capacitors and inductors have been proven to exhibit fractional-order characteristics. Therefore, the establishment of fractional-order models for circuits containing such components is of great significance in practical circuit analysis. This study establishes the impedance models of fractional-order capacitors and inductors based on the Caputo ...

A Method for Designing Multi-Band Rasorbers for Wideband Applications

IEEE Access, 2021
Rasorbers with a single passband (narrow or wide) or multiple narrow passbands have been reported for stealth applications over the past few years. In this work, a method of designing the multi-band rasorber with wide passband(s) is proposed for the ...

High-sensitivity in various gyrator-based circuits with exceptional points of degeneracy

EPJ Applied Metamaterials, 2022
Exceptional points of degeneracy (EPD) can enhance the sensitivity of circuits by orders of magnitude. We show various configurations of coupled LC resonators via a gyrator that support EPDs of second and third-order.
