Abstract :
An electromagnetic invisibility cloak featuring an elliptic inner and a circular outer boundary was presented. Explicit design equations were given. The performance of the designed cloaks for different angles of incidence and shielded object dimensions were verified by full-wave EM simulations. The proposed configuration leads to more flexible geometries for invisibility cloaks.
