Ultralight artificial medium multilayer cylindrical lens

An ultralight artificial medium multilayer cylindrical lens, comprising concentric layers of different dielectric constants, wherein the concentric layers comprise a center cylindrical layer which is a solid cylinder, and annular layers which are in a sequentially outward nested arrangement surrounding the center cylindrical layer;

• the concentric layers are assembled into a multilayer cylinder;
• the dielectric constants of the concentric layers gradually decrease from the center cylindrical layer to an outermost annular layer of the annular layers and vary specifically between 2.05 to 1.05;
• each of the concentric layers comprises a base material of low dielectric constant and an additive material of high dielectric constant and low specific gravity;
• the base material is a light foaming dielectric material, specifically has a density of 0.02-0.03 g/cm3;
• a content of the additive material in the concentric layers per unit volume gradually decreases from the center cylindrical layer to the outermost annular layer.
