This paper describes the design and fabrication of multiband infrared frequency selective surfaces FSSs that consist of selfsimilar fractal cross dipole metallic elements patterned on flexible dielectric substrates. Two transmission stopbands centered at 6.4 THz 15.3 dB and 17.5 THz -6.2 dB were measured on FSSs with primary and secondary cross elements that are 17 m and 7 m long and 1 m wide. These properties correspond well to those predicted by a periodic method of moments model that was used to formulate electromagnetic scattering from this FSS. Future work will include modulating passband frequencies through field-controlled modulations of the physical properties of the substrate.
