Separation of consecutive FSSs frequency bands is possible with wider transmission/reflection bands and also faster roll-off in some of the applications.
Higher order passband FSS can achieve better performance with faster roll-off and smooth in-band frequency response.
Generally, the required qualities of an FSS are wide passband, fast roll-off (sharp edges), and insensitivity to incident angles and polarizations of an incoming EM wave in applications, such as RCS reduction, terahertz sensing, EM compatibility, and telecommunication.
A transmission curve with rectangular shape, sharp roll-off, and wider out-of-band rejection is obtained while five transmission poles within the passband (12.1 to 15.4 GHz) are observed. 3D printing technique is utilized to construct this uncommon structure with photo polymerization using ultraviolet light cured resin.
Ultimately, the strong coupling mechanism provides fast roll-off than any other multilayer FSS designs.
