Breaking the Limitations of Temporal Modulation via Mixed Continuity Conditions
Yongge Wang, Jingfeng Yao, Ying Wang +2
The conventional description of time-varying media assumes that electromagnetic fields evolve according to fixed continuity conditions during parameter jumps. Here we reveal that t…
