All‐Dielectric Frequency Selective Surface Based on 3D Printing Materials

In this paper, the authors demonstrate a method of using low permittivity 3D printing materials to design all‐dielectric frequency selective surface (FSS). The 3D printing method can be used to fabricate complex structures rapidly and freely. The relative permittivity of materials used in 3D printing is in the range of ≈2.5–4.5. These low permittivity materials are usually transparent to the electromagnetic (EM) waves. In this paper, these low permittivity materials are used to realize stop band FSS to inspire the localized enhanced electric resonances and magnetic resonances by the periodic design. With the ability of using different dielectric materials with low permittivity, FSS with more functional effects may be designed and fabricated in an inexpensive and bio‐friendly way.
