Abstract
Provided is an electromagnetic dielectric material (1). The electromagnetic dielectric material (1) is a column structure. The electromagnetic dielectric material (1) includes an inner core (11), a first foam layer (12) and a second foam layer (13) sequentially arranged from inside to outside on the cross section of the column structure. The first foam layer (12) and the second foam layer (13) are each a layer formed from a foam material foamed. The electromagnetic dielectric material further includes metal wires (14). The metal wires (14) 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 (12). Further provided is a method for producing an electromagnetic dielectric material (1).
