Abstract
This paper presents a new category of composite right-left-handed (CL-CRLH) unit cells. The new cells rely on complementary stubs, e.g., open and short circuited stubs in planar transmission lines or dual modes in coupled lines. They have geometrical circuit model, do not rely on commercial off-the-shelf components, and do not require vias. Theoretical expectations have been confirmed by EM simulations and measurements.
