Reconfigurable non-reciprocal wave growth in spatiotemporal modulated 1-D crystal
Mohamed F. Hagag, Thomas R. Jones, Karim Seddik +1
Nonreciprocity in space-time modulated photonic crystals has been investigated in the context of nonreciprocal propagation and polarization. Here, we investigate a reconfigurable n…

Signal Amplification in a Time-Modulated Transmission Line and the Loss Effect
Mohamed Hagag, Thomas Robert Jones, Karim Seddik +1
We investigate and simulate signal amplification in a transmission line (TL) with time-modulated characteristic impedance Zo. Periodically varying is achieved by loading TL w…
