Hai-Wen Liu, Zheng-Fan, Xiao-Wei Sun, Satoshi Kurachi, Jia Chen and Toshihiko Yoshimasu
In this letter, a simple approach to determine slow-wave factors is proposed. Furthermore, a comparison of the dispersion characteristics between DGS unit and periodic DGS is clarified. Also, the slow-wave and fast-wave behaviors of defected ground structures (DGS) unit are investigated and explained by an LC resonator.
