Characterization of Nematic Liquid Crystal Dielectric Properties Using Complementary FSSs Featuring Electrically Small Cell Gaps Across a Wide Sub-THz Range

Dual‐ and triple‐passband coupled‐complementary FSSs based on the four‐arms star geometry

“…Doubleand single-metallic layered structures, supported by only a single substrate, represent closely coupled-complementary FSSs inspired by Babinet's principle. The proposed CFSS uses a non-traditional geometry that has a very easy design process and a simple fabrication process, when compared to some published complementary structures [11,[24][25][26]. The element's geometry and filtering mechanism are presented, showing that the operating frequencies can be adjusted independently.…”
