Aperiodic temporal modulation for distortionless broadband impedance matching beyond the Bode-Fano limit
Martin Olguin-Lopez, Dimitrios L. Sounas, Nader Engheta +2
The Bode-Fano bound sets a fundamental trade-off between bandwidth and reflection in passive, linear, time-invariant matching networks. We show that an aperiodically time-modulated…

Kapitza-Inspired Stabilization of Non-Foster Circuits via Time Modulations
Antonio Alex-Amor, Grigorii Ptitcyn, Nader Engheta
With his formal analysis in 1951, the physicist Pyotr Kapitza demonstrated that an inverted pendulum with an externally vibrating base can be stable in its upper position, thus ove…
