碩士 === 國立交通大學 === 電信工程系 === 91 === This paper focuses on modeling the periodic structure as an impedance surface. Based on the exact formulation, we explore the guiding characteristic of planar corrugated structure and compare the results with the approximated impedance surface method. The comparison shows impedance surface can approximate the structure well. Also, the scattering characteristic is discussed for verifying the guiding characteristic. Combining the impedance surface method and scattering test, we can rapidly get the guiding behavior of a corrugated structure with high accuracy.
