Concept of Virtual Electric/Magnetic Walls and its Realization With Artificial Magnetic Conductor Technique

In this letter, we present a novel concept of virtual electric/magnetic walls which are formed by combining perfect electric conducting parallel plates and perfect magnetic conducting parallel plates. In practice, the perfect magnetic wall can be replaced with an artificial magnetic conductor surface. Two types of complementary transverse electromagnetic waveguides are built with the virtual electric/magnetic walls. The field distribution in the waveguide was simulated and measured. The existence of virtual electric wall was verified.
