Band gap analyses for high impedance electromagnetic surfaces using adaptive finite element method in frequency domain

摘要

An adaptive finite element method in frequency domain (A-FEM-FD) is presented, which is suitable for the band gap analyses of high impedance electromagnetic surfaces. Three new types of EBG structures are simulated and the regions of their in-plane band gaps for both TE and TM modes are given, which are consistent with the test results by Agilent E8363B VNA.
