Provided is an electromagnetic dielectric material (). The electromagnetic dielectric material () is a column structure. The electromagnetic dielectric material () includes an inner core (), a first foam layer () and a second foam layer () sequentially arranged from inside to outside on the cross section of the column structure. The first foam layer () and the second foam layer () are each a layer formed from a foam material foamed. The electromagnetic dielectric material further includes metal wires (). The metal wires () are disposed in the longitudinal direction of the column structure, are not in contact with each other and are evenly distributed on the periphery of the first foam layer (). Further provided is a method for producing an electromagnetic dielectric material ().

Electromagnetic dielectric material and method for producing electromagnetic dielectric material

The present invention provides a better electromagnetic lens, a method for producing it and a lens antenna. The electromagnetic lens is a winded body made of a strip material. The dielectric constant of a dielectric material gradually changes in both a transverse direction and a longitudinal direction of the strip material. After the strip material is winded to be a winded body, the dielectric material is distributed in at least one artificially predetermined three-dimensional space range called a lens body inside the winded body. A part of the winded body besides the lens body is called a non-lens part. The dielectric constant of the lens body is not lower than that the dielectric constant of the non-lens part.
