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…

First-principles analysis of energy exchange in time-varying capacitors for energy trapping applications
Kristy Hecht, David González-Ovejero, Dimitrios L. Sounas +1
Time-varying networks, consisting of lumped elements, such as resistors, capacitors, and inductors, actively modulated in time, have introduced a host of novel wave phenomena and w…
