[7p-N203-12]Floquet Matrix Formulation for Dispersive and Dissipative Time-Varying Media

Keywords:

Time-varying medium,Photonic time crystal

Photonic time crystals (PTC), consisting of periodic time-varying medium (TVM), have recently attracted considerable attention because it shows exotic properties that cannot be realized in static systems, such as magnetic- free non-reciprocity, Floquet harmonic generation, synthetic frequency dimensions, enhanced spontaneous emission rate and others. Hence it is critical to develop a unified framework to describe the dispersion relation and calculate the eigenmodes in PTC, which can be used to derive the topological invariants in TVM.
