In this presentation I
will show the recent progress on metamaterial researches conducted at Southeast
University, China. I will present some new illusion-optics devices, the electromagnetic
black hole, the two-dimensional (2D) compact-size broadband carpet cloak, the
three-dimensional (3D) broadband carpet cloak, 2D and 3D gradient-index planar
lens antennas, and Luneburg lens antenna, all of which are made of metamaterials.
