Ultrabroadband 3D invisibility with fast-light cloaks
Three-dimensional invisibility cloaks are either limited in bandwidth or disregard the phase of the impinging wave or work only in specific directions. Here, the authors report that these restrictions can be lifted by using cloaks made of fast-light media where the wave group velocity is larger than...
