Ideal Optical Antimatter using Passive Lossy Materials under Complex Frequency Excitation
Olivia Y. Long, Peter B. Catrysse, Seunghoon Han +1
The original concept of left-handed material has inspired the possibility of optical antimatter, where the effect of light propagation through a medium can be completely cancelled…

Shaping space-time wavepackets beyond the paraxial limit using a dispersion magnifier
Dongha Kim, Cheng Guo, Peter B. Catrysse +1
Space-time wavepackets (STWPs) have received significant attention since they can propagate in free space at arbitrary group velocity without dispersion and diffraction. However, a…
