Abstract: Provided in the present invention is an ultralight artificial medium multilayer cylindrical lens, comprising n concentric layers of different dielectric constants. The center cylindrical layer is expressed as layer 1 and is a solid cylinder. Layers 2 to n are in a sequentially outward nested arrangement surrounding the center cylindrical layer and respectively are n-1 concentric rings. The n concentric layers are assembled into a multilayer cylinder and are characterized in that the dielectric constants of the n concentric layers gradually decrease from layer 1 to layer n and vary specifically between 2.05 to 1.05. The n concentric layers are made of a base material of low dielectric constant added with a material of high dielectric constant and low specific gravity. The lens so manufactured has a total apparent density of 0.08-0.095 g/cm3.
