Temporal Transfer Matrix Method for Exceptional-Point Media via Canonical Basis Expansion
Neng Wang, Guo Ping Wang
We present a generalized temporal transfer matrix method (TTMM) for time-varying media that accurately captures wave dynamics in media operating at exceptional points (EPs). The me…

Temporal Scattering at Irremovable Exceptional Points in Lossless Drude Media
Neng Wang, Shuyong Chen, Guo Ping Wang
We investigate temporal scattering in lossless Drude media and reveal an overlooked role of the zero-frequency flat band associated with static polarization charge. This flat band…
