Abstract :
In this paper, the reflection phase diagram along with frequency changes of artificial magnetic wall (AMC) is studied and we can determine the frequency band at which the AMC can be achieved. The concept of virtual electric/magnetic walls which are formed by combining perfect electric conducting parallel plates and perfect magnetic conducting parallel plates is cited. In practice, the perfect magnetic wall can be replaced with an artificial magnetic conductor surface. The implement of the Quasi-TEM waveguide with uniplanar compact electromagnetic band gap (UC-EBG) structure is simulated. The field distribution in the waveguide is presented with two simulation methods in HFSS which verifies the existence of the VMW. The phenomena in connection with AMC and resonance are also discussed.
