The coefficients in the empirical formula were determined by using least-square curve fitting technique to fit 672 sets of shifted resonant frequencies obtained by the HFSS simulator. Numerical results of shifted resonant frequencies obtained from the empirical formula are generally in good agreement with those calculated by the HFSS simulator and measurement. The average error in the shifted resonant frequencies is less than 5 percent. The empirical formula thus provides a simple, inexpensive, and quick method for obtaining optimum geometrical parameters of a dual-band Jerusalem-cross FSS with a substrate consisting of different dielectric constants and thickness for arbitrarily specifying two resonant frequencies.</p>}, number={07}, journal={The Applied Computational Electromagnetics Society Journal (ACES)}, author={Hsing-Yi Chen and Shu-Huan Wen}, year={2021}, month={Jul.}, pages={730–740} }
