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…
