摘要：
Dipole-patch infrared (IR) frequency selective surface's (FSS) with resonant responses at wavelengths between 4 and 14 μm were analyzed. The effect of interelement spacing on the location and width of the resonance and the influence of superstrate and substrate refractive indices on the resonance wavelength was investigated. A shift of the resonance toward shorter wavelengths and a slight broadening of the resonance behavior was observed for FSS with closely spaced elements.
