Ea. Parker et A. Stanley, DUAL-POLARIZED NARROW-BANDPASS FREQUENCY-SELECTIVE SURFACES, Microwave and optical technology letters, 13(2), 1996, pp. 105-107
Two arrays of single-ring slots with different radii supported on eith
er side of a thin dielectric substrate form frequency-selective surfac
es (FSSs) with a very narrow bandpass transmission responses. The -10-
dB bandwidths are less than 10%. Their high angular stability, mechani
cal flexibility, and dual polarized performance are features important
in applications such as electromagnetic screening. (C) 1996 John Wile
