Abstract

A novel way to design arbitrarily-shaped retro-reflectors by optic surface transformation is proposed. The entire design process consists of filling an optic-null medium between the input and output surfaces of the retro-reflector, on which the points have 180 degree reverse corresponding relations. The retro-reflector can be designed to be very thin (a planar structure) with high efficiency. The effective working angles of our retro-reflector are very large (from -80 degrees to +80 degrees), which can in principle be further extended. Layered metal plates and zero refractive index materials are designed to realize proposed retro-reflector using for a TM polarized beam.
