摘要：In this talk, we first introduce about transformation optics and some cloak experiments.  Then, we focus on the time-domain cloaks model.  The explicit expressions of the cloak parameters without the contour curve expressions of the objects and 2d arbitrary shape cloaks model are established. A new time domain finite element scheme is developed to solve the governing equations, and its stability is also provided. Then, we give some design methods about cloak devices. Numerical results are presented to confirm the theoretical analysis and the effectiveness of our cloak model and FETD method.
