Investigation of Slow Wave Structure with Metal PBG Structures

摘要：

The dispersion curves of TM modes of two-dimensional (2D) photonic band gap (PBG) structures formed by triangular arrays of metal posts are calculated using Finite-Difference Time-Domain (FDTD) method, and the global frequency band gap of TM modes of the PBG structures with different values of the ration of the post radius (r) to the post spacing (a) are obtained from the calculated dispersion curves. According to the global frequency band gap, a PBG cavity supporting TM01-like mode is designed. Furthermore a Ka band slow wave system with PBG structure is constructed and the electromagnetic characteristic and impedance of which are analyzed.
