In this section, we design an invisible cloak using the composite medium of silver nanowires with elliptical cross-sections embedded in a polymethyl methacrylate host. Under the guidance of an analytical effective medium approach, we use the parameter retrieval method to design a well-performed invisible cloak, based on an empirical revised version of the reduced cloak. The cloak is numerically proved to be robust for both the inner hidden object as well as incoming detecting waves, and is much simpler thus easier to manufacture when compared with the earlier proposed one.
